I noticed that commit 07928d9bfc81 "padata: Remove broken queue
flushing" has been backported to most stable branches, but commit
6fc4dbcf0276 "padata: Replace delayed timer with immediate workqueue in
padata_reorder" has not.

Is this correct?  What prevents the parallel_data ref-count from
dropping to 0 while the timer is scheduled?

Ben.
