Hi Anant,
I see you are testing lots of USB bugs. USB subsystem is currently
broken, testing of any USB bugs will give false "no crash" results,

Fixes for this USB problem are in my tree now and should show up in
linux-next on Monday.

Oh, I see. Thank you for letting me know. I'll be sure to keep that in mind, until I hear
otherwise. :)
Thanks,

Is there any chance you could identify the commit that fixes this bug?
It would help us close the bug for good. :)
Thanks,

I think Greg meant the fix for the general USB brokenness, not a fix
for this syzbot bug. This bug is not fixed to the best of syzbot
knowledge.

Ah, okay. My bad. I was wondering why the bug wasn't closed already
if there was already a fix. Thank you for clearing that up :)
Thanks,
