Because I sent the patch this morning for another report:
https://syzkaller.appspot.com/bug?extid=1e3ea63db39f2b4440e0

Then I asked syzbot for this report to test my branch with that patch
applied and the result is OK.

Is there any way to ask syzbot to test a patch already posted to the mailing
list? (instead of sending it back to it again)

Stefano

I don't know of a way, but hey, sending it back isn't too bad,
just mention this in the mail text.


Okay, I'll do also for another report.

Thanks,
Stefano
