Forgot to mention that this should probably go to stable. Having an

quite hard to debug (e.g. reclaim not considering the movable zone).
I do not expect many users would suffer from this it but still this is
trivial and obviously right thing to do so backporting to the stable
tree shouldn't be harmful (last famous words).

Cc: stable # since 4.13

older tress would have to be checked explicitly.

While the final commit included Michal's response, it didn't have a
stable tag. Could someone confirm it should go in stable?
