I don't know why I got Cc'ed on this :), but I gave it a quick test anyway.

I think you want to at least Cc the atomic folks:
ATOMIC INFRASTRUCTURE M: Will Deacon <will@kernel.org> M: Peter Zijlstra <peterz@infradead.org> R: Boqun Feng <boqun.feng@gmail.com> R: Mark Rutland <mark.rutland@arm.com> L: linux-kernel@vger.kernel.org S: Maintained
