Subject: [PULL v2 10/15] s390x/s390-skeys: prepare for memory devices
Date: Sat, 21 Dec 2024 20:22:04 +0100	[thread overview]
Message-ID: <20241221192209.3979595-11-david@redhat.com> (raw)
In-Reply-To: <20241221192209.3979595-1-david@redhat.com>

With memory devices, we will have storage keys for memory that
exceeds the initial ram size.

The TODO already states that current handling is subopimal,
but we won't worry about improving that (TCG-only) thing for now.

Acked-by: Michael S. Tsirkin <mst@redhat.com>
