Ignoring the STAGING issue I've tried to use the same guideline as for
-stable for -rc ..

So this is a real problem, we definitely hit the locking bugs if we
retry/etc under stress, so I would be OK to send it to Linus for

However, it doesn't look like the 1st patch is fixing a current bug

three are -rc?
