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"

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: don't log the entire end of the AGF
