fd29269606 reiserfs: Use signed i_nlink
Unlike Linux, FreeBSD's kernel doesn't like unsigned file link
count. This is consistent with our ext2fs implementation.

warnings in sys/gnu/fs/xfs.  The only warnings that still need to be
suppressed are those about array bound overruns of flexible array
members in xfs_dir2_{block,sf}.c, which are too expensive (in terms of
cascading code changes) to fix.

50e91f8ce1 Just like the other file systems found in /sys/fs, g_vfs_open()
should be paried with g_vfs_close().  Though g_vfs_close() is a wrapper
around g_wither_geom_close(), r206130 added the following test in
g_vfs_open():

	if (bo->bo_private != vp)
		return (EBUSY);

  Which will cause a 'Device busy' error inside reiserfs_mountfs() if
the same file system is re-mounted again after umount or mounting failure:

	(case 1, /dev/ad4s3 is not a valid REISERFS partition)
	# mount -t reiserfs -o ro /dev/ad4s3 /mnt
	mount: /dev/ad4s3: Invalid argument
	# mount -t msdosfs -o ro /dev/ad4s3 /mnt
	mount: /dev/ad4s3: Device busy

	(case 2, /dev/ad4s3 is a valid REISERFS partition)
	# mount -t reiserfs -o ro /dev/ad4s3 /mnt
	# umount /mnt
	# mount -t reiserfs -o ro /dev/ad4s3 /mnt
	mount: /dev/ad4s3: Device busy

  On the other hand, g_vfs_close() 'fixed' the above cases by doing an
extra step to keep 'sc->sc_bo->bo_private' and 'cp->private' pointers
synchronised.

It seems strchr() and strrchr() are used more often than index() and
rindex(). Therefore, simply migrate all kernel code to use it.

a9d2f8d84f Second-to-last commit implementing Capsicum capabilities in the FreeBSD
kernel for FreeBSD 9.0:

Add a new capability mask argument to fget(9) and friends, allowing system
call code to declare what capabilities are required when an integer file
descriptor is converted into an in-kernel struct file *.  With options
CAPABILITIES compiled into the kernel, this enforces capability
protection; without, this change is effectively a no-op.

Some cases require special handling, such as mmap(2), which must preserve
information about the maximum rights at the time of mapping in the memory
map so that they can later be enforced in mprotect(2) -- this is done by
narrowing the rights in the existing max_protection field used for similar
purposes with file permissions.

In namei(9), we assert that the code is not reached from within capability
mode, as we're not yet ready to enforce namespace capabilities there.
This will follow in a later commit.

Update two capability names: CAP_EVENT and CAP_KEVENT become
CAP_POST_KEVENT and CAP_POLL_KEVENT to more accurately indicate what they
represent.

694a586a43 Add a lock flags argument to the VFS_FHTOVP() file system
method, so that callers can indicate the minimum vnode
locking requirement. This will allow some file systems to choose
to return a LK_SHARED locked vnode when LK_SHARED is specified
for the flags argument. This patch only adds the flag. It
does not change any file system to use it and all callers
specify LK_EXCLUSIVE, so file system semantics are not changed.

d0cc54f3b4 The r184588 changed the layout of struct export_args, causing an ABI
breakage for old mount(2) syscall, since most struct <filesystem>_args
embed export_args. The mount(2) is supposed to provide ABI
compatibility for pre-nmount mount(8) binaries, so restore ABI to
pre-r184588.

3634d5b241 Add dedicated routines to toggle lockmgr flags such as LK_NOSHARE and
LK_CANRECURSE after a lock is created.  Use them to implement macros that
otherwise manipulated the flags directly.  Assert that the associated
lockmgr lock is exclusively locked by the current thread when manipulating
these flags to ensure the flag updates are safe.  This last change required
some minor shuffling in a few filesystems to exclusively lock a brand new
vnode slightly earlier.
