Subject: gunit/test-015: Populate subtree_control for leaf cgroup
X-Git-Tag: v3.1.0~257
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=328ec5e8e4f00790cb91f81ff53f2cdd42d0106f;p=thirdparty%2Flibcgroup.git

gunit/test-015: Populate subtree_control for leaf cgroup

We no more rely on the cgroup's parent subtree_control file to verify
if a controller is enabled for a cgroup. So, populate the leaf/child
cgroups with subtree_control file similar to the parent cgroup.
