Subject[PATCH 0/7] KVM: syzkaller fixes
Date
These fix most of the bugs reported by Dmitry Vyukov a while back.
I couldn't reproduce one of the bugs (patch 7) but the fix is easy.
Probably, more VM ioctls should take kvm->lock, but I have not looked
at it yet.

I have only marked for stable the two patches that fix an oops. However,
all of patches 1-6 could go in 4.7-rc, I think.

Thanks,

Paolo
