So I'm afraid that I have some bad news about this patch, it fixes the RCU warning which I reported: https://lore.kernel.org/linux-wireless/20210104170713.66956-1-hdegoede @redhat.com/ But it introduces a deadlock. See: https://lore.kernel.org/linux-wireless/d839ab62-e4bc-56f0-d861-f172bf1 9c4b3@redhat.com/ for details. Note we really should fix this new deadlock before 5.11 is released. This is worse then the RCU warning which this patch fixes.Ouch. Thanks for the heads-up. I guess I'll revert both patches for now, unless we can quickly figure out a way to get all these paths in order.
Thanks Hans and Johannes for handling this. I'll try to come up with a solution. Regards, Ilan.
