Subject: [PATCH 1/6] cgroup/cpuset: Rename functions dealing with DEADLINE accounting
Date: Mon, 21 Aug 2023 23:19:51 +0100 [thread overview]
Message-ID: <20230821221956.698117-2-qyousef@layalina.io> (raw)
In-Reply-To: <20230821221956.698117-1-qyousef@layalina.io>
From: Juri Lelli <juri.lelli@redhat.com>
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.
