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

Pull quota and UDF fix from Jan Kara:
 "A fix for UDF to properly free preallocated blocks and a fix for quota
  so that Q_GETQUOTA quotactl reports correct numbers for XFS filesystem
  (and similarly Q_XGETQUOTA quotactl works properly for other
  filesystems)"

* 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs:
  quota: Switch ->get_dqblk() and ->set_dqblk() to use bytes as space units
  udf: Release preallocation on last writeable close
