Shuah, I just got this new report from 0-day about your commit
0c9e8b3cad65 ("usbip: usbip_host: fix BUG: sleeping function called from
invalid context") that got added to my tree recently. Can you look into
this to see if it is a real error caused by this commit, or just
something that has always been there?
Thanks Greg. I think this is a new problem introduced in my patch. I
will send the fix.
thanks,
-- Shuah
