Hello,

this is a second revision of my patches to convert ext4 DAX IO paths to the new
iomap framework and removes the old bh-based DAX functions. As a result ext4
gains PMD page fault support, also some other minor bugs get fixed. The patch
set is based on Ross' DAX PMD page fault support series [1]. It passes xfstests
both in DAX and non-DAX mode.

I have pushed out updated version of these patches including the follow-up
DAX patches to:

git://get.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs.git dax

for easy testing. Once Dave pushes out a stable branch with Ross' patches, we
pull those into ext4 tree and then pull these patches on top of that (provided
nobody will have other objections to the current series).

Done:

git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs.git dax-4.10-iomap-pmd

Cheers,

Dave.
