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

Pull UDF fixes and cleanups from Jan Kara:
 "Several small UDF fixes and cleanups and a small cleanup of fanotify
  code"

* 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs:
  fanotify: simplify the code of fanotify_merge
  udf: simplify udf_ioctl()
  udf: fix ioctl errors
  udf: allow implicit blocksize specification during mount
  udf: check partition reference in udf_read_inode()
  udf: atomically read inode size
  udf: merge module informations in super.c
  udf: remove next_epos from udf_update_extent_cache()
  udf: Factor out trimming of crtime
  udf: remove empty condition
  udf: remove unneeded line break
  udf: merge bh free
  udf: use pointer for kernel_long_ad argument
  udf: use __packed instead of __attribute__ ((packed))
  udf: Make stat on symlink report symlink length as st_size
  fs/udf: make #ifdef UDF_PREALLOCATE unconditional
  fs: udf: Replace CURRENT_TIME with current_time()
