Merge tag 'xfs-iomap-for-linus-4.8-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs
Pull xfs and iomap fixes from Dave Chinner:
 "Most of these changes are small regression fixes that address problems
  introduced in the 4.8-rc1 window.  The two fixes that aren't (IO
  completion fix and superblock inprogress check) are fixes for problems
  introduced some time ago and need to be pushed back to stable kernels.

  Changes in this update:
   - iomap FIEMAP_EXTENT_MERGED usage fix
   - additional mount-time feature restrictions
   - rmap btree query fixes
   - freeze/unmount io completion workqueue fix
   - memory corruption fix for deferred operations handling"

* tag 'xfs-iomap-for-linus-4.8-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs:
  xfs: track log done items directly in the deferred pending work item
  iomap: don't set FIEMAP_EXTENT_MERGED for extent based filesystems
  xfs: prevent dropping ioend completions during buftarg wait
  xfs: fix superblock inprogress check
  xfs: simple btree query range should look right if LE lookup fails
  xfs: fix some key handling problems in _btree_simple_query_range
  xfs: don't log the entire end of the AGF
  xfs: disallow mounting of realtime + rmap filesystems
  xfs: don't perform lookups on zero-height btrees
