Hello, this patch set converts 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. The question is how shall we merge this. If Dave is pulling PMD patches through XFS tree, then these patches could go there as well (chances for conflicts with other ext4 stuff are relatively low) or Dave could just export a stable branch with PMD series which Ted would just pull...
