Anything received after that time might be too late.


AFAICS the warning problems are still seen. Unfortunately I won't be able
to bisect since I have limited internet access.

Isn't this a fallout of:

queue-5.14/net-introduce-and-use-lock_sock_fast_nested.patch
that has: Fixes: 2dcb96bacce3 ("net: core: Correct the sock::sk_lock.owned lockdep annotations")

BUT:

$ git describe --contains 2dcb96bacce3
v5.15-rc3~30^2~26
