Subject: [PATCH] sched: add kernel-doc for set_cpus_allowed_ptr
Date: Tue, 29 Aug 2023 11:25:51 +0300 [thread overview]
Message-ID: <20230829082551.2661290-1-costa.shul@redhat.com> (raw)
This is an exported symbol, so it should have kernel-doc.
Add a note to very similar function do_set_cpus_allowed
to avoid confusion and misuse.
