From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
Currently we reuse the commit_work for a later cleanup step.
Let's not do that so that atomic ioctl handler won't accidentally
wait for the cleanup work when it really wants to just wait on the
commit_tail() part. We'll just add another work struct for the
cleanup.
