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.
