Hmm ... even with that patch applied, I still see the crash reported in my 
previous email. After I observed that crash I did a clean kernel build to 
make sure that the kernel binaries used in my test match the source code.

I still can't reproduce it at all.  With this patchset on Jens'
for-5.18/block branch I do get a pre-existing crash in
nvmf_connect_admin_queue, and on Jens' for-next tree that has all the
latest fixes from Linus' tree I only see the CM lockdep warning you
reported.

FYI, this is a branch with the patches applied ontop of the for-next
branch:
