Merge tag 'gfs2-4.8.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2...

Pull gfs2 updates from Bob Peterson:
 "We've only got six GFS2 patches for this merge window.  In patch
  order:

   - Fabian Frederick submitted a nice cleanup that uses the BIT macro
     rather than bit shifting.

   - Andreas Gruenbacher contributed a patch that fixes a long-standing
     annoyance whereby GFS2 warned about dirty pages.

   - Andreas also fixed a problem with the recent extended attribute
     readahead feature.

   - Chao Yu contributed a patch that checks the return code from
     function register_shrinker and reacts accordingly. Previously, it
     was not checked.

   - Andreas Gruenbacher also fixed a problem whereby incore file
     timestamps were forgotten if the file was invalidated. This merely
     moves the assignment inside the inode glock where it belongs.

   - Andreas also fixed a problem where incore timestamps were not
     initialized"
