xfs: for-next branch updated to 4d50b3b

Hi folks,

The for-next branch of the xfs kernel repository at

git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs.git

has just been updated. This includes various fixes and cleanups, a bunch of iomap and XFS prep work for reflink, a delayed allocation rework optimised for the new iomap infrastructure, and a DAX implementation for the iomap infrastructure. Both XFS and ext2 are switched over to the new DAX iomap infrastructure.

Christoph and Ross - if there's anything in that I shouldn't have merged, then let me know. There are no apparent xfstests regressions that I've seen, so it all looks good from my perspective....

-Dave.

The new head of the for-next branch is commit:

4d50b3b Merge branch 'iomap-4.9-dax' into for-next
