Subject: [PATCH 0/2] s390/vfio-ap: do not open code locks for VFIO_GROUP_NOTIFY_SET_KVM notification

This series is actually only comprised of a single patch to replace the
open coded locks used during VFIO_GROUP_NOTIFY_SET_KVM notification. The
first patch is included because it is a pre-req slotted to be merged but is
not yet available in the kernel.
