Subject: [PATCH 1/6] cgroup/cpuset: Rename functions dealing with DEADLINE accounting
From: Juri Lelli <juri.lelli@...hat.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.
