Yeah, so I've taken the rest as well, it all looks very clean now. Should show up
in the next -next, if it passes my (arguably limited) testing.

Andrew, is this workflow fine with you? You usually take KASAN patches, but I was
unhappy with the atomics instrumention of the earlier patches, and ended up
reviewing the followup variants, and felt that if I hinder a patchset I might as
well test and apply it once I'm happy with them! ;-)

Should be a special exception for this series only.
