reiserfs: Use signed i_nlink

2014-09-25T19:10:32+00:00

Unlike Linux, FreeBSD's kernel doesn't like unsigned file link
count. This is consistent with our ext2fs implementation.

r16312 is not any longer real since many years (likely since when VFS

2012-11-19T22:43:45+00:00

received granular locking) but the comment present in UFS has been
copied all over other filesystems code incorrectly for several times.

Removes comments that makes no sense now.

Complete MPSAFE VFS interface and remove MNTK_MPSAFE flag.

Porters should refer to __FreeBSD_version 1000021 for this change as
it may have happened at the same timeframe.

Just like the other file systems found in /sys/fs, g_vfs_open()

2012-08-01T23:05:57+00:00

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.
