There was one comment that I am not sure if it was emailed and that
was about adding the "lockdep_assert_held(&swap_lock);".

You added that in two patches, while the git commit only talks about
"move that code" . Please remove it out of the "move the code" patches
and add it as a seperate git commit with an explanation of why it
is added.

Otherwise (well, the compile issue that was spotted) the patches
look great. Could you repost them with those two fixes please?
