This patchset includes all the filesystem and iomap changes needed to support transparent huge pages. A separate patchset will enable the MM side of things. I'm hoping Darrick agrees to take the first two patches through the iomap tree, These patches are for review. They don't currently apply to the iomap tree due to some conflicting patches. I'll rebase on top of -rc1 once it's out (they do apply to 5.9).
