I dug up the synchronous patch
https://lore.kernel.org/lkml/1579878449-10164-1-git-send-email-prsood@codeaurora.org/
but surprisingly wasn't able to reproduce the lockdep splat from
https://lore.kernel.org/lkml/F0388D99-84D7-453B-9B6B-EEFF0E7BE4CC@lca.pw/
even though I could hit it a few weeks ago. I'm going to try to mess with it later, but don't let me hold this up.
