SubjectRe: [PATCH 0/2] s390/vfio-ap: do not open code locks for VFIO_GROUP_NOTIFY_SET_KVM notification
From
Date
PING!

This patch will pre-req version 17 of a patch series I have waiting in
the wings,
so I'd like to get this one merged ASAP. In particular, if a KVM
maintainer can
take a look at the comments concerning the taking of the kvm->lock
before the
matrix_mdev->lock it would be greatly appreciated. Those comments begin with
Message ID <20210727004329.3bcc7d4f.pasic@linux.ibm.com> from Halil Pasic.
