    Merge tag 'xfs-for-linus-3.15-rc5' of git://oss.sgi.com/xfs/xfs
    
    Pull xfs fixes from Dave Chinner:
     "The main fix is adding support for default ACLs on O_TMPFILE opened
      inodes to bring XFS into line with other filesystems.  Metadata CRCs
      are now also considered well enough tested to be fully supported, so
      we're removing the shouty warnings issued at mount time for
      filesystems with that format.  And there's transaction block
      reservation overrun fix.
    
      Summary:
       - fix a remote attribute size calculation bug that leads to a
         transaction overrun
       - add default ACLs to O_TMPFILE files
       - Remove the EXPERIMENTAL tag from filesystems with metadata CRC
         support"

    Merge tag 'ext4_for_linus_stable' of 
git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4
    
    Pull ext4 fixes from Ted Ts'o:
     "These are regression and bug fixes for ext4.
    
      We had a number of new features in ext4 during this merge window
      (ZERO_RANGE and COLLAPSE_RANGE fallocate modes, renameat, etc.) so
      there were many more regression and bug fixes this time around.  It
      didn't help that xfstests hadn't been fully updated to fully stress
      test COLLAPSE_RANGE until after -rc1"

commit 23fffa925ea2c9a2bcb1a4453e2c542635aa3545
Author: Lukas Czerner <lczerner@xxxxxxxxxx>

    fs: move falloc collapse range check into the filesystem methods
    
    Currently in do_fallocate in collapse range case we're checking
    whether offset + len is not bigger than i_size.  However there is
    nothing which would prevent i_size from changing so the check is
    pointless.  It should be done in the file system itself and the file
    system needs to make sure that i_size is not going to change.  The
    i_size check for the other fallocate modes are also done in the
    filesystems.
    
    As it is now we can easily crash the kernel by having two processes
    doing truncate and fallocate collapse range at the same time.  This
    can be reproduced on ext4 and it is theoretically possible on xfs even
    though I was not able to trigger it with this simple test.
    
    This commit removes the check from do_fallocate and adds it to the
    file system.
