Subject: [PATCH v4 3/7] lib/test_cpumask: Add for_each_cpu_and(not) tests
Date: Fri, 23 Sep 2022 16:55:38 +0100 [thread overview]
Message-ID: <20220923155542.1212814-2-vschneid@redhat.com> (raw)
In-Reply-To: <20220923132527.1001870-1-vschneid@redhat.com>
Following the recent introduction of for_each_andnot(), add some tests to
ensure for_each_cpu_and(not) results in the same as iterating over the
result of cpumask_and(not)().
Suggested-by: Yury Norov <yury.norov@gmail.com>
