I don't think much went wrong here. Keeping the [1/4] xfs patch in
mm.git is appropriate, as it's part of a series. Unfortunately Kefeng's
standalone "xfs: fix NOFS state corruption in btree split worker"
conflicted with it.

I suppose I could add the standalone fix to mm-git as well (with xfs
maintainer acks), just to make life easier for everyone?
