Subject: [RFC 0/4] cgroup hierarchy controls and stats
X-Mailer: git-send-email 2.13.3
Creating cgroup hierearchies of an unreasonable size can affect
system performance. A user might want to limit the size
of the cgroup hierarchy.
This patchset implements an ability to control and monitor cgroup
hierarchy size.
Patch 1 implements tracking of live and dying descendant cgroups
on each cgroup level.
Patch 2 adds cgroup.max.descendants and cgroup.max.depth interfaces
to set up hierarchy limits.
Patch 3 adds cgroup.stat interface with simple hierarchy stats.
Patch 4 is a trivial cleanup.
Roman Gushchin (4):
cgroup: keep track of number of descent cgroups
cgroup: implement hierarchy limits
cgroup: add cgroup.stat interface with basic hierarchy stats
cgroup: re-use the parent pointer in cgroup_destroy_locked()
