I dug up the synchronous patch https://lore.kernel.org/lkml/1579878449-10164-1-git-send-email-prsood@xxxxxxxxxxxxxx/ but surprisingly wasn't able to reproduce the lockdep splat from https://lore.kernel.org/lkml/F0388D99-84D7-453B-9B6B-EEFF0E7BE4CC@xxxxxx/ even though I could hit it a few weeks ago.
