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 udf: Ignore [ug]id=ignore mount options udf: Fix handling of Partition Descriptors udf: Unify common handling of descriptors udf: Convert descriptor index definitions to enum udf: Allow volume descriptor sequence to be terminated by unrecorded block udf: Simplify handling of Volume Descriptor Pointers udf: Fix off-by-one in volume descriptor sequence length inotify: Extend ioctl to allow to request id of new watch descriptor
