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). Changes since v1: * Changed ext4_iomap_begin() and ext4_iomap_end() to not keep transaction handle running between these two functions as that causes lock ordering issues.
