Subject: [RFC PATCH 0/2] workqueue: Fix hotplug races

While triggering rcutorture splats, I couldn't trace down to the exact
cause due to the issue being tracing-unfriendly. But looking at the code,
those two potential races look like plausible causes and also after
these two patches, I couldn't reproduce the rcutorture issues again (yet...).
