And it had some useful info:
[PATCH 0/7] Consolidate vcpu ioctl locking
In general, all vcpu ioctls need to take the vcpu mutex, but each one
does it
(or not) individually. This is cumbersome and error prone.
This patchset moves all locking to a central place. This is complicated
by the fact that ppc's KVM_INTERRUPT and s390's KVM_S390_INTERRUPT break
the convention and need to run unlocked.
