The title stays "remove deprecated create_singlethread_workqueue" and if
we put aside the word "deprecated", the code moves from ordered
workqueue to unordered workqueue and changes max_active count which
isn't expressed in commit message.

For reclaim paths, I want to be extra caution and want to see
justification for doing that along with understanding if it is tested or
not.

Right now, I'm feeling that I'm participating in soapie where one sends
patch for every line, waits and sends the same patch for another file.
It is worth to send one patch set and let us to test it all in once.

Thanks.
