Subject: [PATCH v4 3/5] cgroup/cpuset: Rename update_unbound_workqueue_cpumask to update_exclusion_cpumasks
Date: Tue,  6 May 2025 11:15:38 +0200	[thread overview]
Message-ID: <20250506091534.42117-10-gmonaco@redhat.com> (raw)
In-Reply-To: <20250506091534.42117-7-gmonaco@redhat.com>

The function calls the workqueue_unbound_exclude_cpumask function when
there's a change in isolated CPUs. The function 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.
