Could you please retry with attached patches?
I was able to reproduce an GPF with a similar test by running xfstests
from Steve's for-next branch with
'vers=3.1.1,multichannel,max_channels=2'
against Windows Server 2022.
No deadlocks or lockdep warnings. The deadlock fix from second patch
was just based on code analysis.
Thanks.
I'll test and report back.
