Yes. I haven't sent the patch for that reason. I am trying to test a
solution. I haven't come up with a solution yet.

Holding event_lock isn't the right solution. I am not going to accept
that. This is a window that gets triggered by syzbot injecting errors
in a sequence. Fixing this should be done taking other moving parts of
the driver into account.

What is event_lock ? I questioned you what the event_lock is at
https://lkml.kernel.org/r/3dab66dc-2981-bc88-a370-4b3178dfd390@i-love.sakura.ne.jp ,
but you haven't responded to that post.

Also, you need to send https://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux.git/commit/?h=usbip_test&id=f345de0d2e51a20a2a1c30fc22fa1527670d2095
because Greg already sent this regression into upstream and stable kernels.

I acked it when it came in and it will be picked up.

thanks,
