[PATCH v4 0/2] KVM: selftests: fix races in dirty log test

[Peter Xu <peterx@redhat.com>]

v4:
- add missing vcpu_handle_sync_stop() call in dirty ring test

The other solution of patch 2 is here [1]

I got another report that there seems to still be a race, but that one seems
extremely hard to trigger, even so far we don't know whether that could be
ARM-only.  Since current fix should make sense already and fix real problems,
IMHO we don't need to wait for that.

Paolo, I still kept the 2nd patch just for completeness, but feel free to
ignore the 2nd patch if you prefer the other version, and I'll follow your
preference.

Thanks!
