Right now this series is in a stable branch in the XFS tree:

If you want to push it through some other tree, please let me know
when/where it is committed so I can rebuild the XFS for-next branch
appropriately from a stable commit/branch...

That's how I think it should be handled.  This would also allow the
ext4 and ocfs2 maintainers to depend on the stable branch to clean
up their direct I/O completion handling in this merge window if they
want to.
