The rests can wait until 5.3.
Sure - how close is this to a straight:
git revert 70800c3c0cc5
?
If it's close enough then please resubmit this as a 'Revert "..."' patch, which I'll queue up in locking/urgent.
It also is a performance, not a correctness fix, and should probably get a Cc: stable as well, right?
In any case it doesn't directly affect the locking/core bits pull request for Linus, 70800c3c0cc5 is already upstream.
Thanks,
Ingo
