4.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johannes Berg <johannes.berg@xxxxxxxxx>
commit ce162bfbc0b601841886965baba14877127c7c7c upstream.
We're obviously not part of a memory reclaim path, so don't set the flag.
This also causes a warning in check_flush_dependency() since we end up
in a code path that flushes a non-reclaim workqueue, and we shouldn't do
that if we were really part of reclaim.
