You may need to be more precise about the tree that you are using as
linux-next rebases every day and so there could be different
interactions with a single commit depending on what else is in a
particular release.  For example, the above commit appears in 4
different linux-next releases so far (next-20150204, next-20150209,
next-20150210, next-20150211).

Also, mm related problems should probably also be reported to Andrew
Morton.
