Merge branch 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs

Pull UDF, reiserfs, quota, fsnotify cleanups from Jan Kara:
"Several UDF, reiserfs, quota and fsnotify cleanups.

Note that there is also a patch updating MAINTAINERS entry for
notification subsystem to point to me as a maintainer since current
entries are stale"

* 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs:
fsnotify: make dnotify_fsnotify_ops const
isofs: Delete an unnecessary variable initialisation in isofs_read_inode()
isofs: Adjust four checks for null pointers
isofs: Delete an error message for a failed memory allocation in isofs_read_inode()
quota_v2: Delete an error message for a failed memory allocation in v2_read_file_info()
fs-udf: Delete an error message for a failed memory allocation in two functions
fs-udf: Improve six size determinations
fs-udf: Adjust two checks for null pointers
reiserfs: fix spelling mistake: "tranasction" -> "transaction"
MAINTAINERS: Update entries for notification subsystem
uapi/linux/quota.h: Do not include linux/errno.h
