Subject: [PATCH v1 5/9] KVM: s390: selftest: memop: Replace macros by functions
Date: Fri, 30 Sep 2022 23:07:47 +0200	[thread overview]
Message-ID: <20220930210751.225873-6-scgl@linux.ibm.com> (raw)
In-Reply-To: <20220930210751.225873-1-scgl@linux.ibm.com>

Replace the DEFAULT_* test helpers by functions, as they don't
need the exta flexibility.
