[PATCH 1/6] cgroup/cpuset: Rename functions dealing with DEADLINE accounting

From: Qais Yousef
Date: Sun Aug 20 2023 - 11:25:08 EST


From: Juri Lelli <juri.lelli@xxxxxxxxxx>

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.
