Not sure it still matters but I was suggesting that creating
apply_workqueue_attrs_locked() which requires the caller to handle
locking and making apply_workqueue_attrs() a wrapper which grabs and
releases lock around it, and using the former in locked iteration
would work.  lol has this explanation made it any clearer or is it
even worse now?  :)
