Is that right? So just for getting idea what the changes are about and to run some tests you can use my unstable branch which Dave mentioned: git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs.git dax As Christoph had some review comments, I'll be updating that probably tomorrow when I have tested updated series. I'll also add some other iomap related patches that were sitting later in my branch after DAX mmap changes but which, as I realized, don't really depend on them. WRT the merging the plan is Dave will take all patches that are prerequisite for this series and push them out in a stable branch which you can then pull into your tree to merge ext4 iomap changes.
