This seems to be more of an mm thing than a filesystem thing? I don't
see any code changes on the filesystem side from a quick scan, just
renaming?

Are there any behavioural changes for the filesystem to be aware of?

How's it been tested, any considerations there?

If this is as simple as it looks, ack from me (and if it is that simply,
why so many recipients?).

If there are _any_ behavioural changes on the mm side that might
interact with the filesystem in funny ways, please make sure the whole
fstests suite has been run.
