1.1	23-Dec-2002	jdolecek	branches: 1.1.2; move adosfs files from sys/adosfs to sys/fs/adosfs
1.1.2.2	29-Dec-2002	thorpej	With with HEAD.
1.1.2.1	23-Dec-2002	thorpej	file Makefile was added on branch nathanw_sa on 2002-12-29 19:55:24 +0000
1.22	06-Aug-2022	andvar	s/blity/bility/ in various words, mainly in comments.
1.21	17-Jan-2020	ad	VFS_VGET(), VFS_ROOT(), VFS_FHTOVP(): give them a "int lktype" argument, to allow us to get shared locks (or no lock) on the returned vnode. Matches FreeBSD.
1.20	03-Sep-2018	riastradh	branches: 1.20.6; Rename min/max -> uimin/uimax for better honesty. These functions are defined on unsigned int. The generic name min/max should not silently truncate to 32 bits on 64-bit systems. This is purely a name change -- no functional change intended. HOWEVER! Some subsystems have #define min(a, b) ((a) < (b) ? (a) : (b)) #define max(a, b) ((a) > (b) ? (a) : (b)) even though our standard name for that is MIN/MAX. Although these may invite multiple evaluation bugs, these do _not_ cause integer truncation. To avoid `fixing' these cases, I first changed the name in libkern, and then compile-tested every file where min/max occurred in order to confirm that it failed -- and thus confirm that nothing shadowed min/max -- before changing it. I have left a handful of bootloaders that are too annoying to compile-test, and some dead code: cobalt ews4800mips hp300 hppa ia64 luna68k vax acorn32/if_ie.c (not included in any kernels) macppc/if_gm.c (superseded by gem(4)) It should be easy to fix the fallout once identified -- this way of doing things fails safe, and the goal here, after all, is to _avoid_ silent integer truncations, not introduce them. Maybe one day we can reintroduce min/max as type-generic things that never silently truncate. But we should avoid doing that for a while, so that existing code has a chance to be detected by the compiler for conversion to uimin/uimax without changing the semantics until we can properly audit it all. (Who knows, maybe in some cases integer truncation is actually intended!)
1.19	07-Feb-2014	hannken	branches: 1.19.28; 1.19.30; Change vnode operation lookup to return the resulting vnode *vpp unlocked. Change cache_lookup() to return an unlocked vnode. Discussed on tech-kern@ Welcome to 6.99.31
1.18	05-Nov-2012	dholland	branches: 1.18.2; Excise struct componentname from the namecache. This uglifies the interface, because several operations need to be passed the namei flags and cache_lookup also needs for the time being to be passed cnp->cn_nameiop. Nonetheless, it's a net benefit. The glop should be able to go away eventually but requires structural cleanup elsewhere first. This change requires a kernel bump.
1.17	05-Nov-2012	dholland	Disentangle the namecache from the internals of namei. - Move the namecache's hash computation to inside the namecache code, instead of being spread out all over the place. Remove cn_hash from struct componentname and delete all uses of it. - It is no longer necessary (if it ever was) for cache_lookup and cache_lookup_raw to clear MAKEENTRY from cnp->cn_flags for the cases that cache_enter already checks for. - Rearrange the interface of cache_lookup (and cache_lookup_raw) to make it somewhat simpler, to exclude certain nonexistent error conditions, and (most importantly) to make it not require write access to cnp->cn_flags. This change requires a kernel bump.
1.16	22-Jul-2012	rmind	branches: 1.16.2; Move some the test for MAKEENTRY into the cache_enter(9). Make some variables in vfs_cache.c static, __read_mostly, etc. No objection on tech-kern@.
1.15	30-Nov-2010	dholland	branches: 1.15.8; 1.15.14; Abolish the SAVENAME and HASBUF flags. There is now always a buffer, so the path in a struct componentname is now always valid during VOP calls.
1.14	24-Jun-2010	hannken	Clean up vnode lock operations pass 2: VOP_UNLOCK(vp, flags) -> VOP_UNLOCK(vp): Remove the unneeded flags argument. Welcome to 5.99.32. Discussed on tech-kern.
1.13	08-Jan-2010	pooka	branches: 1.13.2; 1.13.4; The VATTR_NULL/VREF/VHOLD/HOLDRELE() macros lost their will to live years ago when the kernel was modified to not alter ABI based on DIAGNOSTIC, and now just call the respective function interfaces (in lowercase). Plenty of mix'n match upper/lowercase has creeped into the tree since then. Nuke the macros and convert all callsites to lowercase. no functional change
1.12	14-Mar-2009	dsl	ANSIfy another 1261 function definitions. The only ones left in sys are beyond by sed script! (or in sys/dist or sys/external) Mostly they have function pointer parameters.
1.11	26-Nov-2007	pooka	branches: 1.11.18; 1.11.26; 1.11.32; Remove the "struct lwp *" argument from all VFS and VOP interfaces. The general trend is to remove it from all kernel interfaces and this is a start. In case the calling lwp is desired, curlwp should be used. quick consensus on tech-kern
1.10	10-Oct-2007	ad	branches: 1.10.4; Merge from vmlocking: - Split vnode::v_flag into three fields, depending on field locking. - simple_lock -> kmutex in a few places. - Fix some simple locking problems.
1.9	09-Dec-2006	chs	branches: 1.9.6; 1.9.18; 1.9.20; 1.9.22; a smorgasbord of improvements to vnode locking and path lookup: - LOCKPARENT is no longer relevant for lookup(), relookup() or VOP_LOOKUP(). these now always return the parent vnode locked. namei() works as before. lookup() and various other paths no longer acquire vnode locks in the wrong order via vrele(). fixes PR 32535. as a nice side effect, path lookup is also up to 25% faster. - the above allows us to get rid of PDIRUNLOCK. - also get rid of WANTPARENT (just use LOCKPARENT and unlock it). - remove an assumption in layer_node_find() that all file systems implement a recursive VOP_LOCK() (unionfs doesn't). - require that all file systems supply vfs_vptofh and vfs_fhtovp routines. fill in eopnotsupp() for file systems that don't support being exported and remove the checks for NULL. (layerfs calls these without checking.) - in union_lookup1(), don't change refcounts in the ISDOTDOT case, just adjust which vnode is locked. fixes PR 33374. - apply fixes for ufs_rename() from ufs_vnops.c rev. 1.61 to ext2fs_rename().
1.8	14-May-2006	elad	branches: 1.8.8; 1.8.10; 1.8.12; integrate kauth.
1.7	11-Dec-2005	christos	branches: 1.7.4; 1.7.6; 1.7.8; 1.7.10; 1.7.12; merge ktrace-lwp.
1.6	26-Feb-2005	perry	branches: 1.6.4; nuke trailing whitespace
1.5	24-Feb-2004	wiz	branches: 1.5.8; 1.5.10; achieved, not acheived. From Peter Postma.
1.4	24-Feb-2004	wiz	becuase -> because. From Peter Postma.
1.3	29-Jun-2003	fvdl	branches: 1.3.2; Back out the lwp/ktrace changes. They contained a lot of colateral damage, and need to be examined and discussed more.
1.2	28-Jun-2003	darrenr	Pass lwp pointers throughtout the kernel, as required, so that the lwpid can be inserted into ktrace records. The general change has been to replace "struct proc " with "struct lwp " in various function prototypes, pass the lwp through and use l_proc to get the process pointer when needed. Bump the kernel rev up to 1.6V
1.1	23-Dec-2002	jdolecek	branches: 1.1.2; move adosfs files from sys/adosfs to sys/fs/adosfs
1.1.2.2	29-Dec-2002	thorpej	With with HEAD.
1.1.2.1	23-Dec-2002	thorpej	file adlookup.c was added on branch nathanw_sa on 2002-12-29 19:55:25 +0000
1.3.2.7	04-Mar-2005	skrll	Sync with HEAD. Hi Perry!
1.3.2.6	21-Sep-2004	skrll	Fix the sync with head I botched.
1.3.2.5	18-Sep-2004	skrll	Sync with HEAD.
1.3.2.4	24-Aug-2004	skrll	Undo part of the ktrace/lwp changes. In particular: * Remove the "lwp " argument that was added to vget(). Turns out that nothing actually used it! Remove the "lwp " arguments that were added to VFS_ROOT(), VFS_VGET(), and VFS_FHTOVP(); all they did was pass it to vget() (which, as noted above, didn't use it). Remove all of the "lwp *" arguments to internal functions that were added just to appease the above.
1.3.2.3	03-Aug-2004	skrll	Sync with HEAD
1.3.2.2	03-Jul-2003	wrstuden	LWP-ify adosfs. Also remove unused variable size from adosfs_mount(). Note: These changes suffer from the same cnp->cn_lwp issue noted for ufs. They will need to get fixed at the same time as ufs. The fix is to add struct lwp * as a parameter to some VOPs.
1.3.2.1	02-Jul-2003	darrenr	Apply the aborted ktrace-lwp changes to a specific branch. This is just for others to review, I'm concerned that patch fuziness may have resulted in some errant code being generated but I'll look at that later by comparing the diff from the base to the branch with the file I attempt to apply to it. This will, at the very least, put the changes in a better context for others to review them and attempt to tinker with removing passing of 'struct lwp' through the kernel.

1.9.6.1	17-Jun-2007	ad	- Increase the number of thread priorities from 128 to 256. How the space is set up is to be revisited. - Implement soft interrupts as kernel threads. A generic implementation is provided, with hooks for fast-path MD code that can run the interrupt threads over the top of other threads executing in the kernel. - Split vnode::v_flag into three fields, depending on how the flag is locked (by the interlock, by the vnode lock, by the file system). - Miscellaneous locking fixes and improvements.

1.9	28-Jun-2008	rumble	branches: 1.9.4; 1.9.10; Create sysctl entries during module initialisation and destroy them appropriately. Many of these file systems are now ready for modularisation.
1.8	03-Dec-2005	christos	branches: 1.8.70; 1.8.74; 1.8.76; 1.8.78; - protect userland exported files against multiple inclusion. - make sure that kernel only files don't compile in userland using #error - XXX: some kernel only files still get installed. - XXX: some files used in userland, don't get installed.
1.7	25-Sep-2005	jmmv	Follow compat naming tradition: rename compat_export_args to export_args30.
1.6	23-Sep-2005	jmmv	Apply the NFS exports list rototill patch: - Remove all NFS related stuff from file system specific code. - Drop the vfs_checkexp hook and generalize it in the new nfs_check_export function, thus removing redundancy from all file systems. - Move all NFS export-related stuff from kern/vfs_subr.c to the new file sys/nfs/nfs_export.c. The former was becoming large and its code is always compiled, regardless of the build options. Using the latter, the code is only compiled in when NFSSERVER is enabled. While doing this, also make some functions in nfs_subs.c conditional to NFSSERVER. - Add a new command in nfssvc(2), called NFSSVC_SETEXPORTSLIST, that takes a path and a set of export entries. At the moment it can only clear the exports list or append entries, one by one, but it is done in a way that allows setting the whole set of entries atomically in the future (see the comment in mountd_set_exports_list or in doc/TODO). - Change mountd(8) to use the nfssvc(2) system call instead of mount(2) so that it becomes file system agnostic. In fact, all this whole thing was done to remove a 'XXX' block from this utility! - Change the mount, newfs and fsck userland utilities to not deal with NFS exports initialization; done internally by the kernel when initializing the NFS support for each file system. - Implement an interface for VFS (called VFS hooks) so that several kernel subsystems can run arbitrary code upon receipt of specific VFS events. At the moment, this only provides support for unmount and is used to destroy NFS exports lists from the file systems being unmounted, though it has room for extension. Thanks go to yamt@, chs@, thorpej@, wrstuden@ and others for their comments and advice in the development of this patch.
1.5	26-Feb-2005	perry	branches: 1.5.4; nuke trailing whitespace
1.4	13-Sep-2004	jdolecek	branches: 1.4.4; 1.4.6; set mp->mnt_stat.f_namemax on filesystem mount for use by statvfs, and use the value for also pathconf(_PC_NAME_MAX) to keep the two in sync
1.3	20-May-2004	atatat	Tweak sysctl setup functions (the macros, actually) for use in lkms, and tweak lkminit_*.c (where applicable) to call them, and to call sysctl_teardown() when being unloaded. This consists of (1) making setup functions not be static when being compiled as lkms (change to sys/sysctl.h), (2) making prototypes visible for the various setup functions in header files (changes to various header files), and (3) making simple "load" and "unload" functions in the actual lkminit stuff. linux_sysctl.c also needs its root exposed (ie, made not static) for this (when built as an lkm).
1.2	01-Feb-2003	thorpej	branches: 1.2.2; 1.2.4; Add extensible malloc types, adapted from FreeBSD. This turns malloc types into a structure, a pointer to which is passed around, instead of an int constant. Allow the limit to be adjusted when the malloc type is defined, or with a function call, as suggested by Jonathan Stone.

1.17	05-Aug-2014	hannken	Change adosfs from hashlist to vcache. - point ap->block to real file header block for hard links.
1.16	27-Feb-2014	hannken	branches: 1.16.2; The current implementation of vn_lock() is racy. Modification of the vnode operations vector for active vnodes is unsafe because it is not known whether deadfs or the original file system will be called. - Pass down LK_RETRY to the lock operation (hint for deadfs only). - Change deadfs lock operation to return ENOENT if LK_RETRY is unset. - Change all other lock operations to check for dead vnode once the vnode is locked and unlock and return ENOENT in this case. With these changes in place vnode lock operations will never succeed after vclean() has marked the vnode as VI_XLOCK and before vclean() has changed the operations vector. Adresses PR kern/37706 (Forced unmount of file systems is unsafe) Discussed on tech-kern. Welcome to 6.99.33
1.15	12-Jun-2011	rmind	branches: 1.15.2; 1.15.12; 1.15.16; Welcome to 5.99.53! Merge rmind-uvmplock branch: - Reorganize locking in UVM and provide extra serialisation for pmap(9). New lock order: [vmpage-owner-lock] -> pmap-lock. - Simplify locking in some pmap(9) modules by removing P->V locking. - Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs). - Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner. Add TLBSTATS option for x86 to collect statistics about TLB shootdowns. - Unify /dev/mem et al in MI code and provide required locking (removes kernel-lock on some ports). Also, avoid cache-aliasing issues. Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches formed the core changes of this branch.

1.10	14-Mar-2009	dsl	Change about 4500 of the K&R function definitions to ANSI ones. There are still about 1600 left, but they have ',' or /* ... */ in the actual variable definitions - which my awk script doesn't handle. There are also many that need () -> (void). (The script does handle misordered arguments.)

Remove the "lwp " arguments that were added to VFS_ROOT(), VFS_VGET(), and VFS_FHTOVP(); all they did was pass it to vget() (which, as noted above, didn't use it). Remove all of the "lwp *" arguments to internal functions that were added just to appease the above.
1.2.2.1	03-Jul-2003	wrstuden	LWP-ify adosfs. Also remove unused variable size from adosfs_mount(). Note: These changes suffer from the same cnp->cn_lwp issue noted for ufs. They will need to get fixed at the same time as ufs. The fix is to add struct lwp * as a parameter to some VOPs.

1.25	23-Sep-2005	jmmv	Apply the NFS exports list rototill patch: - Remove all NFS related stuff from file system specific code. - Drop the vfs_checkexp hook and generalize it in the new nfs_check_export function, thus removing redundancy from all file systems. - Move all NFS export-related stuff from kern/vfs_subr.c to the new file sys/nfs/nfs_export.c. The former was becoming large and its code is always compiled, regardless of the build options. Using the latter, the code is only compiled in when NFSSERVER is enabled. While doing this, also make some functions in nfs_subs.c conditional to NFSSERVER. - Add a new command in nfssvc(2), called NFSSVC_SETEXPORTSLIST, that takes a path and a set of export entries. At the moment it can only clear the exports list or append entries, one by one, but it is done in a way that allows setting the whole set of entries atomically in the future (see the comment in mountd_set_exports_list or in doc/TODO). - Change mountd(8) to use the nfssvc(2) system call instead of mount(2) so that it becomes file system agnostic. In fact, all this whole thing was done to remove a 'XXX' block from this utility! - Change the mount, newfs and fsck userland utilities to not deal with NFS exports initialization; done internally by the kernel when initializing the NFS support for each file system. - Implement an interface for VFS (called VFS hooks) so that several kernel subsystems can run arbitrary code upon receipt of specific VFS events. At the moment, this only provides support for unmount and is used to destroy NFS exports lists from the file systems being unmounted, though it has room for extension. Thanks go to yamt@, chs@, thorpej@, wrstuden@ and others for their comments and advice in the development of this patch.

Needs kernel option FFS_SNAPSHOT. - Change parameters of ffs_blkfree. - Let the copy-on-write functions return an error so spec_strategy may fail if the copy-on-write fails. - Change genfs_lock() to use vp->v_vnlock instead of &vp->v_lock. - Add flag B_METAONLY to VOP_BALLOC to return indirect block buffer. - Add a function ffs_checkfreefile needed for snapshot creation. - Add special handling of snapshot files: Snapshots may not be opened for writing and the attributes are read-only. Use the mtime as the time this snapshot was taken. Deny mtime updates for snapshot files. - Add function transferlockers to transfer any waiting processes from one lock to another. - Add vfsop VFS_SNAPSHOT to take a snapshot and make it accessible through a vnode. - Add snapshot support to ls, fsck_ffs and dump. Welcome to 2.0F. Approved by: Jason R. Thorpe <thorpej@netbsd.org>
1.16	25-May-2004	atatat	Sysctl descriptions under vfs subtree
1.15	20-May-2004	atatat	Explicitly call pool_init() (and pool_destroy()) when being built as an _LKM. This adds pools to the list of things that lkms must do manually because they're set up with link sets. Not that there's anything wrong with link sets, but that we need to try harder to remember that lkms are second class citizens. Of a sort.
1.14	27-Apr-2004	jrf	First pass for some caddr_t removal and changes to get rid of it where we no longer use and/or need it - removed casts from unionfs, deadfs and fdesc (there are more to hunt down still) - changed vfs_quotactl args argumet from caddr_t to void * - changed vfs_quotactl structures/callers to reflect the api change Compiled fine and ran for about a day. Approved/reviewed by christos@netbsd.org and gimpy@netbsd.org.
1.13	25-Apr-2004	simonb	Initialise (most) pools from a link set instead of explicit calls to pool_init. Untouched pools are ones that either in arch-specific code, or aren't initialiased during initial system startup. Convert struct session, ucred and lockf to pools.
1.12	21-Apr-2004	christos	Replace the statfs() family of system calls with statvfs(). Retain binary compatibility.
1.11	27-Mar-2004	atatat	branches: 1.11.2; Manually attach malloc types when being built as an lkm.
1.10	24-Mar-2004	atatat	Tango on sysctl_createv() and flags. The flags have all been renamed, and sysctl_createv() now uses more arguments.
1.9	04-Dec-2003	atatat	Dynamic sysctl. Gone are the old kern_sysctl(), cpu_sysctl(), hw_sysctl(), vfs_sysctl(), etc, routines, along with sysctl_int() et al. Now all nodes are registered with the tree, and nodes can be added (or removed) easily, and I/O to and from the tree is handled generically. Since the nodes are registered with the tree, the mapping from name to number (and back again) can now be discovered, instead of having to be hard coded. Adding new nodes to the tree is likewise much simpler -- the new infrastructure handles almost all the work for simple types, and just about anything else can be done with a small helper function. All existing nodes are where they were before (numerically speaking), so all existing consumers of sysctl information should notice no difference. PS - I'm sorry, but there's a distinct lack of documentation at the moment. I'm working on sysctl(3/8/9) right now, and I promise to watch out for buses.
1.8	29-Jun-2003	fvdl	branches: 1.8.2; Back out the lwp/ktrace changes. They contained a lot of colateral damage, and need to be examined and discussed more.
1.7	29-Jun-2003	thorpej	Fix problems with the ktrace/lwp changes.
1.6	29-Jun-2003	darrenr	More changes for providing lwpid for ktrace (sparc GENERIC built)
1.5	28-Jun-2003	darrenr	Pass lwp pointers throughtout the kernel, as required, so that the lwpid can be inserted into ktrace records. The general change has been to replace "struct proc " with "struct lwp " in various function prototypes, pass the lwp through and use l_proc to get the process pointer when needed. Bump the kernel rev up to 1.6V
1.4	16-Apr-2003	christos	PR/1796: John Kohl: statfs misbehaves under chrooted environments. - Under chroot it displays only the visible filesystems with appropriate paths. - The statfs f_mntonname gets adjusted to contain the real path from root. - While was there, fixed a bug in ext2fs, locking problems with vfs_getfsstat(), and factored out some of the vfsop statfs() code to copy_statfs_info(). This fixes the problem where some filesystems forgot to set fsid. - Made coda look more like a normal fs.
1.3	21-Mar-2003	dsl	Use 'void *' instead of 'caddr_t' in prototypes of VOP_IOCTL, VOP_FCNTL and VOP_ADVLOCK, delete casts from callers (and some to copyin/out).
1.2	01-Feb-2003	thorpej	Add extensible malloc types, adapted from FreeBSD. This turns malloc types into a structure, a pointer to which is passed around, instead of an int constant. Allow the limit to be adjusted when the malloc type is defined, or with a function call, as suggested by Jonathan Stone.
1.1	23-Dec-2002	jdolecek	branches: 1.1.2; move adosfs files from sys/adosfs to sys/fs/adosfs

1.8.2.7	26-Aug-2004	skrll	Missed these in the vget, etc changes.
1.8.2.6	24-Aug-2004	skrll	Undo part of the ktrace/lwp changes. In particular: * Remove the "lwp " argument that was added to vget(). Turns out that nothing actually used it! Remove the "lwp " arguments that were added to VFS_ROOT(), VFS_VGET(), and VFS_FHTOVP(); all they did was pass it to vget() (which, as noted above, didn't use it). Remove all of the "lwp *" arguments to internal functions that were added just to appease the above.
1.8.2.5	13-Aug-2004	skrll	Adapt to branch. cats GENERIC compiles.
1.8.2.4	12-Aug-2004	skrll	Sync with HEAD.
1.8.2.3	03-Aug-2004	skrll	Sync with HEAD
1.8.2.2	03-Jul-2003	wrstuden	LWP-ify adosfs. Also remove unused variable size from adosfs_mount(). Note: These changes suffer from the same cnp->cn_lwp issue noted for ufs. They will need to get fixed at the same time as ufs. The fix is to add struct lwp * as a parameter to some VOPs.
1.8.2.1	02-Jul-2003	darrenr	Apply the aborted ktrace-lwp changes to a specific branch. This is just for others to review, I'm concerned that patch fuziness may have resulted in some errant code being generated but I'll look at that later by comparing the diff from the base to the branch with the file I attempt to apply to it. This will, at the very least, put the changes in a better context for others to review them and attempt to tinker with removing passing of 'struct lwp' through the kernel.

1.58	27-Mar-2022	christos	dedup the eofs link/symlink methods
1.57	18-Jul-2021	dholland	Abolish all the silly indirection macros for initializing vnode ops tables. These are things of the form #define foofs_op genfs_op, or #define foofs_op genfs_eopnotsupp, or similar. They serve no purpose besides obfuscation, and have gotten cutpasted all over everywhere.
1.56	29-Jun-2021	dholland	- Add a new vnode op: VOP_PARSEPATH. - Move namei_getcomponent to genfs_vnops.c and call it genfs_parsepath. - Add a parsepath entry to every vnode ops table. VOP_PARSEPATH takes a directory vnode to be searched and a complete following path and chooses how much of that path to consume. To begin with, all parsepath calls are genfs_parsepath, which locates the first '/' as always. Note that the call doesn't take the whole struct componentname, only the string. The other bits of struct componentname should not be needed and there's no reason to cause potential complications by exposing them.
1.55	27-Jun-2020	christos	branches: 1.55.6; Introduce genfs_pathconf() and use it for the default case in all filesystems.
1.54	16-May-2020	christos	Add ACL support for FFS. From FreeBSD.
1.53	23-Apr-2020	ad	PR kern/54759 (vm.ubc_direct deadlock when read()/write() into mapping of itself) - Add new flag UBC_ISMAPPED which tells ubc_uiomove() the object is mmap()ed somewhere. Use it to decide whether to do direct-mapped copy, rather than poking around directly in the vnode in ubc_uiomove(), which is ugly and doesn't work for tmpfs. It would be nicer to contain all this in UVM but the filesystem provides the needed locking here (VV_MAPPED) and to reinvent that would suck more. - Rename UBC_UNMAP_FLAG() to UBC_VNODE_FLAGS(). Pass in UBC_ISMAPPED where appropriate.
1.52	23-Apr-2020	jdolecek	fix obvious typo in error handling - buf error should go to b_error
1.51	17-Jan-2020	ad	branches: 1.51.4; VFS_VGET(), VFS_ROOT(), VFS_FHTOVP(): give them a "int lktype" argument, to allow us to get shared locks (or no lock) on the returned vnode. Matches FreeBSD.
1.50	26-May-2017	riastradh	branches: 1.50.10; 1.50.16; Make VOP_RECLAIM do the last unlock of the vnode. VOP_RECLAIM naturally has exclusive access to the vnode, so having it locked on entry is not strictly necessary -- but it means if there are any final operations that must be done on the vnode, such as ffs_update, requiring exclusive access to it, we can now kassert that the vnode is locked in those operations. We can't just have the caller release the last lock because some file systems don't use genfs_lock, and require the vnode to remain valid for VOP_UNLOCK to work, notably unionfs.
1.49	11-Apr-2017	riastradh	Make VOP_INACTIVE preserve vnode lock on return. Discussed on tech-kern: https://mail-index.netbsd.org/tech-kern/2017/04/01/msg021751.html Ride 7.99.68, a bumpy bus of incremental vfs improvements!

1.45	05-Aug-2014	hannken	branches: 1.45.4; Change adosfs from hashlist to vcache. - point ap->block to real file header block for hard links.
1.44	25-Jul-2014	dholland	Add VOP_FALLOCATE and VOP_FDISCARD to every vnode ops table I can find. The filesystem ones all call genfs_eopnotsupp - right now I am only implementing the plumbing and we can implement fallocate and/or fdiscard for files later. The device ones call spec_fallocate (which is also genfs_eopnotsupp) and spec_fdiscard, which dispatches to the device-level op. The fifo ones all call vn_fifo_bypass, which also ends up being EOPNOTSUPP.
1.43	23-Jan-2014	hannken	branches: 1.43.2; Change vnode operations create, mknod, mkdir and symlink to return the resulting vnode *vpp unlocked. Discussed on tech-kern@ Welcome to 6.99.30

1.41	18-Mar-2013	plunky	branches: 1.41.6; C99 section 6.7.2.3 (Tags) Note 3 states that: A type specifier of the form enum identifier without an enumerator list shall only appear after the type it specifies is complete. which means that we cannot pass an "enum vtype" argument to kauth_access_action() without fully specifying the type first. Unfortunately there is a complicated include file loop which makes that difficult, so convert this minimal function into a macro (and capitalize it). (ok elad@)

1.34	23-Jun-2009	elad	Move the implementation of vaccess() to genfs_can_access(), in line with the other routines of the same spirit. Adjust file-system code to use it.

1.7	25-Jan-2004	hannken	Make VOP_STRATEGY(bp) a real VOP as discussed on tech-kern. VOP_STRATEGY(bp) is replaced by one of two new functions: - VOP_STRATEGY(vp, bp) Call the strategy routine of vp for bp. - DEV_STRATEGY(bp) Call the d_strategy routine of bp->b_dev for bp. DEV_STRATEGY(bp) is used only for block-to-block device situations.
1.6	29-Jun-2003	fvdl	branches: 1.6.2; Back out the lwp/ktrace changes. They contained a lot of colateral damage, and need to be examined and discussed more.
1.5	29-Jun-2003	thorpej	Fix problems with the ktrace/lwp changes.
1.4	27-Jan-2003	lonewolf	Fix compiler warnings after 64bit daddr_t change.
1.3	24-Jan-2003	fvdl	Bump daddr_t to 64 bits. Replace it with int32_t in all places where it was used on-disk, so that on-disk formats remain the same. Remove ufs_daddr_t and ufs_lbn_t for the time being.
1.2	09-Jan-2003	lonewolf	Don't scale file block numbers. Fixes mmap() and UBCified read() problems. Reviewed by Ignatios.
1.1	23-Dec-2002	jdolecek	branches: 1.1.2; move adosfs files from sys/adosfs to sys/fs/adosfs

1.6.2.4	18-Sep-2004	skrll	Sync with HEAD.
1.6.2.3	24-Aug-2004	skrll	Undo part of the ktrace/lwp changes. In particular: * Remove the "lwp " argument that was added to vget(). Turns out that nothing actually used it! Remove the "lwp " arguments that were added to VFS_ROOT(), VFS_VGET(), and VFS_FHTOVP(); all they did was pass it to vget() (which, as noted above, didn't use it). Remove all of the "lwp *" arguments to internal functions that were added just to appease the above.

1.6.2.1	03-Jul-2003	wrstuden	LWP-ify adosfs. Also remove unused variable size from adosfs_mount(). Note: These changes suffer from the same cnp->cn_lwp issue noted for ufs. They will need to get fixed at the same time as ufs. The fix is to add struct lwp * as a parameter to some VOPs.

1.16.2.3	19-Nov-2005	yamt	- as read-ahead context is per-vnode now, there are less reasons to make VOP_READ call uvm_ra_request explicitly. move it to pager (uvn_get) so that it can handle accesses via mmap as well. - pass advice to pager via ubc. - tweak DPRINTF. XXX can be disturbed by PGO_LOCKED. XXX it's controversial where it should be done. (uvm_fault, uvn_get or genfs_getpages.)
1.16.2.2	18-Nov-2005	yamt	- associate read-ahead context to vnode, rather than file. - revert VOP_READ prototype.
1.16.2.1	15-Nov-2005	yamt	adapt the rest of filesystems which use genfs_getpages.

1.23.2.1	19-Aug-2007	ad	- Back out the biodone() changes. - Eliminate B_ERROR (from HEAD).
1.24.10.2	29-Jul-2007	ad	It's not a good idea for device drivers to modify b_flags, as they don't need to understand the locking around that field. Instead of setting B_ERROR, set b_error instead. b_error is 'owned' by whoever completes the I/O request.
