Subject: [PATCH v12 5/9] cgroup/cpuset: Rename update_unbound_workqueue_cpumask() to update_exclusion_cpumasks()
Date: Mon, 15 Sep 2025 16:59:26 +0200 [thread overview]
Message-ID: <20250915145920.140180-16-gmonaco@redhat.com> (raw)
In-Reply-To: <20250915145920.140180-11-gmonaco@redhat.com>
update_unbound_workqueue_cpumask() updates unbound workqueues settings
when there's a change in isolated CPUs, but it can be used for other
subsystems requiring updated when isolated CPUs change.
Generalise the name to update_exclusion_cpumasks() to prepare for other
functions unrelated to workqueues to be called in that spot.
