One obstacle there is we currently don't have a way to say "this
workqueue belongs to this cgroup" as there is no "this" cgroup defined
(awesome design).  That part is being rectified but for the time being
we can probably say "this workqueue belongs to the same cgroups as
%current" which should be enough for aio contexts, I think.

Or maybe we should just add current->wq which always matches cgroup
associations of the task?
