 1.30  18-Sep-2021  christos Change the default for ACLs to be posix1e instead of nfsv4 to match FreeBSD.
Requested by chuq.
 1.29  16-May-2020  christos Add ACL support for FFS. From FreeBSD.
 1.28  19-Oct-2012  drochner Implement experimental support to pass notifications that a file
was deleted from the filesystem to the disk driver, commonly
known as "discard" or "trim".
fs/driver support is in ffs and ata wd for now.
This is what was posted here:
http://mail-index.netbsd.org/tech-kern/2012/02/28/msg012813.html
with minor cleanup, and the global switch replaced by a mount option.
 1.27  29-Aug-2011  joerg branches: 1.27.2; 1.27.8;
Use __dead
 1.26  17-Jun-2011  manu Add mount -o extattr option to enable extended attributs (corrently only
for UFS1).
Remove kernel option for EA backing store autocreation and do it by
default. Add a sysctl so that autocreated attriutr size can be modified.
 1.25  05-Aug-2008  pooka branches: 1.25.10; 1.25.18;
Refactor mount utilities to provide a mount_fs_parseargs() routine.
Use this routine both in mount_fs and rump_fs to provide equivalent
command line parameters and therefore usage interchangeability.
While doing this, combine some common mountgoop to mountprog.h
 1.24  31-Jul-2008  simonb Merge the simonb-wapbl branch. From the original branch commit:

Add Wasabi System's WAPBL (Write Ahead Physical Block Logging)
journaling code. Originally written by Darrin B. Jewell while
at Wasabi and updated to -current by Antti Kantee, Andy Doran,
Greg Oster and Simon Burge.

OK'd by core@, releng@.
 1.23  20-Jul-2008  lukem Remove the \n and tabs from the __COPYRIGHT() strings.
(Tweak some to use a consistent format.)
 1.22  16-Jul-2007  pooka branches: 1.22.12; 1.22.16; 1.22.18;
Make all mount(2) return value error checks against -1. Some file
systems just checked != 0, breaking MNT_GETARGS. Others worked with < 0,
but make them check against -1 too for consistency. And sprinkle some
stylish line wrapping where appropriate.
 1.21  14-Jul-2007  dsl Add additional 'sizeof args' parameter to mount(2).
 1.20  16-Oct-2006  christos use MOPT_NULL
 1.19  21-Mar-2006  christos Always check the results of getmntopts() and free them.
 1.18  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.
 1.17  05-Feb-2005  xtraeme ll __P(), use ANSI function declarations; WARNS=3.
 1.16  31-Jan-2005  erh Fix PR#3617 and PR#3205: call realpath to convert mount points and paths to
device nodes into absolute paths before using them.
 1.15  07-Aug-2003  agc Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22308, verified by myself.
 1.14  22-Mar-2003  jdolecek use <> rather than "" for #include mntopts.h
 1.13  21-Sep-2002  christos MNT_GETARGS support
 1.12  30-Oct-2000  jdolecek make the code includable into other programs:
* make static all symbols which do not need to be exported
* rename main() to mount_FOO()
* new main() now just calls mount_FOO(), main() is only compiled in if
MOUNT_NOMAIN is not defined
* a_gid(), a_uid() and a_mask() were put into ../mount/fattr.[ch], local
versions removed
 1.11  15-Jun-2000  fvdl Enable -o softdep.
 1.10  14-Apr-2000  simonb branches: 1.10.2;
Don't declare 'extern opt*' getopt variables.
 1.9  01-Dec-1998  kenh Add support for a new flag: "nodevmtime". This sets the MNT_NODEVMTIME mount
flag.
 1.8  26-Jul-1998  mycroft const poisoning.
 1.7  01-Mar-1998  fvdl Merge with Lite2 + local changes
 1.6  16-Sep-1997  lukem apply mods from lite-2 vers. of mount/mount_ufs.c (which this is derived from)
 1.5  15-Sep-1997  lukem * update for WARNS=1

 1.4  30-Jan-1997  tls add support for noatime mount flag
 1.3  13-Apr-1996  jtc Add const qualifier to mopts table
 1.2  11-Nov-1995  mycroft MOUNT_UFS -> MOUNT_FFS, and remove bogus comment.
 1.1  12-Jul-1995  cgd branches: 1.1.2;
split FFS mount code out of mount(8). the correct way to name fast file
systems is now 'ffs', though 'ufs' is tolerated in fstab for backward
compatibility.
 1.1.2.1  01-Nov-1995  jtc complete ufs -> ffs change (From John Kohl; PR #1403)
 1.10.2.1  22-Jun-2000  minoura Sync w/ netbsd-1-5-base.
 1.22.18.2  28-Jul-2008  simonb Sync with head.
 1.22.18.1  10-Jun-2008  simonb Initial commit of Wasabi System's WAPBL (Write Ahead Physical Block
Logging) journaling code. Originally written by Darrin B. Jewell
while at Wasabi and updated to -current by Antti Kantee, Andy Doran,
Greg Oster and Simon Burge.

Still a number of issues - look in doc/BRANCHES for "simonb-wapbl"
for more info.
 1.22.16.1  18-Sep-2008  wrstuden Sync with wrstuden-revivesa-base-2.
 1.22.12.1  28-Sep-2008  mjf Sync with HEAD.
 1.25.18.1  23-Jun-2011  cherry Catchup with rmind-uvmplock merge.
 1.25.10.3  21-Oct-2010  uebayasi After consideration, put back "xip" mount option.

The internal behavior is totally different between with and without
the option; automatic detection and/or fall-through are not user
friendly. mount(8) returning the "xip" flag is also informative.
 1.25.10.2  28-May-2010  uebayasi Remove the "xip" option from mount_ffs(8) for simplicity.
 1.25.10.1  11-Feb-2010  uebayasi Support the "xip" option.
 1.27.8.1  20-Nov-2012  tls Resync to 2012-11-19 00:00:00 UTC
