Subject: [kvm-unit-tests PATCH v3 2/6] s390x: sclp: Remove unnecessary padding from struct sclp_facilities
Date: Tue, 21 Apr 2026 13:31:08 +0200 [thread overview]
Message-ID: <20260421-vsie-stfle-fac-v3-2-3cee84efefa3@linux.ibm.com> (raw)
In-Reply-To: <20260421-vsie-stfle-fac-v3-0-3cee84efefa3@linux.ibm.com>
Struct sclp_facilities is only used within the guest to keep the facility
information. Nothing bad should happen when the struct size changes in the
future.
