I thought we had already agreed to run these patches through the ext4
git tree, since most of the changes affect the ext4 tree (and there
aren't any other iomap fiemap changes pending as far as I know).

The v3 versions of these patches have been part of the ext4 dev tree
since May 19th.  Since the ext4 dev tree is rewinding, I can easily
update it fiemap-fixes patch to be on top of the first two patches
which Linus has already accepted, and then merge it into the ext4 dev
branch.
