    Linus Torvalds authored
    Pull ext4 updates from Ted Ts'o:
     "Fix a number of bugs, most notably a potential stale data exposure
      after a crash and a potential BUG_ON crash if a file has the data
      journalling flag enabled while it has dirty delayed allocation blocks
      that haven't been written yet.  Also fix a potential crash in the new
      project quota code and a maliciously corrupted file system.
      In addition, fix some DAX-specific bugs, including when there is a
      transient ENOSPC situation and races between writes via direct I/O and
      an mmap'ed segment that could lead to lost I/O.
      Finally the usual set of miscellaneous cleanups"
