Subject: [PATCH v16 4/7] cgroup/cpuset: Rename update_unbound_workqueue_cpumask() to update_isolation_cpumasks()
Date: Thu, 20 Nov 2025 15:56:50 +0100 [thread overview]
Message-ID: <20251120145653.296659-5-gmonaco@redhat.com> (raw)
In-Reply-To: <20251120145653.296659-1-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_isolation_cpumasks() to prepare for other
functions unrelated to workqueues to be called in that spot.
[longman: Change the function name to update_isolation_cpumasks()]
