Subject: [PATCH 1/6] cgroup/cpuset: Rename functions dealing with DEADLINE accounting
Date: Sun, 20 Aug 2023 16:22:53 +0100	[thread overview]
Message-ID: <20230820152258.518128-2-qyousef@layalina.io> (raw)
In-Reply-To: <20230820152258.518128-1-qyousef-wp2msK0BRk8tq7phqP6ubQ@public.gmane.org>

From: Juri Lelli <juri.lelli-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>

commit ad3a557daf6915296a43ef97a3e9c48e076c9dd8 upstream.

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.
