Hi all,

I've stumbled on the following while fuzzing with trinity inside a KVM tools guest, running on 3.5-rc2:

Thanks for the report, it could be worth adding this one to
bugzilla.kernel.org.

What's trinity ?
Also, if this one is reproducible, would you mind sharing some details about
how we could reproduce it ?

Well, bugfix should be trivial enough ;)

Yep, I looked at the code only after looking at Sasha's report.

Thanks for the patch, do you mind if I add your SOB to it ?

I  would prefer making sure it fixes the bug first ;)

Sure, although your patch makes sense regardless of that :)
I'll still wait for Sasha to confirm that it fixes his crash.

I don't have a direct way of reproducing it, but I've put it in the test
vm and the fuzzer is running, I'll let you know tomorrow if it happened
again.
