OK I guess this is fine... :)

An aside, unrelated tot his series: it'd be nice to use 'deflate' consistently
in this code. We do __count_vm_event(BALLOON_DEFLATE) in
balloon_page_list_dequeue() but say 'deflate' nowhere else... well before this
patch :)

Right, dequeue is actually deflate, because one couldn't use that 
function for anything else as it stands.

TODO list ... :)
