Subject: [PATCH v2 1/6] cgroup/cpuset: Rename functions dealing with DEADLINE accounting
Date: Wed, 3 May 2023 09:22:23 +0200 [thread overview]
Message-ID: <20230503072228.115707-2-juri.lelli@redhat.com> (raw)
In-Reply-To: <20230503072228.115707-1-juri.lelli@redhat.com>
rebuild_root_domains() and update_tasks_root_domain() have neutral
names, but actually deal with DEADLINE bandwidth accounting.
Rename them to use 'dl_' prefix so that intent is more clear.
No functional change.
