hannken | branches: 1.23.10; Remove now unused VV_LOCKSWORK, all file systems support locking.
Remove unused predicates vn_locked() and vn_anylocked().
Welcome to 9.99.95

riastradh | Round of uvm.h cleanup.
The poorly named uvm.h is generally supposed to be for uvm-internal users only.
- Narrow it to files that actually need it -- mostly files that need to query whether curlwp is the pagedaemon, which should maybe be exposed by an external header.
- Use uvm_extern.h where feasible and uvm_*.h for things not exposed by it. We should split up uvm_extern.h but this will serve for now to reduce the uvm.h dependencies.
- Use uvm_stat.h and #ifdef UVMHIST uvm.h for files that use UVMHIST(ubchist), since ubchist is declared in uvm.h but the reference evaporates if UVMHIST is not defined, so we reduce header file dependencies.
- Make uvm_device.h and uvm_swap.h independently includable while here.

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.

maxv | branches: 1.11.2; An (un)privileged user can easily make the kernel dereference a NULL pointer.
The kernel allows 'data' to be NULL; it's the fs's responsibility to ensure that it isn't NULL (if the fs actually needs data).

hannken | Replace macro v_specmountpoint with two functions spec_node_getmountedfs() and spec_node_setmountedfs() to manage the file system mounted on a device. Assert the device is a block device.
Welcome to 6.99.24
Discussed on tech-kern@ some time ago.

1.7 |
| 22-Jan-2013 |
dholland | branches: 1.7.2; Stuff UFS_ in front of a few of ufs's symbols to reduce namespace pollution. Specifically: ROOTINO -> UFS_ROOTINO WINO -> UFS_WINO NXADDR -> UFS_NXADDR NDADDR -> UFS_NDADDR NIADDR -> UFS_NIADDR MAXSYMLINKLEN -> UFS_MAXSYMLINKLEN MAXSYMLINKLEN_UFS[12] -> UFS[12]_MAXSYMLINKLEN (for consistency)
Sort out ext2fs's misuse of NDADDR and NIADDR; fortunately, these have the same values in ext2fs and ffs.
No functional change intended.

pgoyette | Adapt machine-independant code to the new {b,c}devsw reference-counting (using localcount(9)). All callers of {b,c}devsw_lookup() now call {b,c}devsw_lookup_acquire() which retains a reference on the 'struct {b,c}devsw'. This reference must be released by the caller once it is finished with the structure's content (or other data that would disappear if the 'struct {b,c}devsw' were to disappear).
