Ok, everybody seems to like that more, and it removes code rather than adds it, so I certainly prefer it too. Paweł, can you test that other patch (to mm/migrate.c) that Hugh posted? Instead of the mremap vma locking patch that you already verified for your setup?
Hugh - that one didn't have a changelog/sign-off, so if you could write that up, and Paweł's testing is successful, I can apply it... Looks like we have acks from both Andrea and Mel.
