Merge branch 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs
Pull misc filesystem updates from Jan Kara:
"udf, ext2, quota, fsnotify fixes & cleanups:
- udf fixes for handling of media without uid/gid
- udf fixes for some corner cases in parsing of volume recognition
sequence
- improvements of fsnotify handling of ENOMEM
- new ioctl to allow setting of watch descriptor id for inotify (for
checkpoint - restart)
- small ext2, reiserfs, quota cleanups"
* 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs:
quota: Kill an unused extern entry form quota.h
reiserfs: Remove VLA from fs/reiserfs/reiserfs.h
udf: fix potential refcnt problem of nls module
ext2: change return code to -ENOMEM when failing memory allocation
udf: Do not mark possibly inconsistent filesystems as closed
fsnotify: Let userspace know about lost events due to ENOMEM
fanotify: Avoid lost events due to ENOMEM for unlimited queues
udf: Remove never implemented mount options
udf: Update mount option documentation
udf: Provide saner default for invalid uid / gid
udf: Clean up handling of invalid uid/gid
udf: Apply uid/gid mount options also to new inodes & chown
