Subject: wrappers: Add a cgroup_get_cgroup_name API
X-Git-Tag: v0.41~98
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ca32d88ef56b12e207a2b1fe87c08f91e607a7da;p=thirdparty%2Flibcgroup.git

wrappers: Add a cgroup_get_cgroup_name API

We had no way of getting the name from the cgroup structure. We
have enough users who do want this information. Provide an API
to do so.
