No worry about this, I will add a "Cc: <stable@xxxxxxxxxxxxxxx>" tag
to the patch, and the stable folks (or their scripts) will pick it up.


Thanks for that!

This patch works well against the reproducer, this simplified repro and
the longer repro which syzkaller generated couldn't trigger any hang
with the below patch applied.

Great, thanks! Can I add
Reported-and-tested-by: Harshit Mogalapalli <harshit.m.mogalapalli@xxxxxxxxxx>
to the patch?

Sure, that would be good!

Thanks,
Harshit
