Subject: [kvm-unit-tests PATCH v4 9/9] s390x: sclp: Add CPU entry offset comment
Date: Tue, 12 Jan 2021 08:20:54 -0500 [thread overview]
Message-ID: <20210112132054.49756-10-frankja@linux.ibm.com> (raw)
In-Reply-To: <20210112132054.49756-1-frankja@linux.ibm.com>
Let's make it clear that there is something at the end of the
struct. The exact offset is reported by the cpu_offset member.
