Subject: cgroup: Make cgroup_attach a public function
X-Git-Tag: lxc-0.8.0-rc2~46
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=28f2ae839d00373d093234ffbc9bbb4ef5f9d10e;p=thirdparty%2Flxc.git

cgroup: Make cgroup_attach a public function

lxc-attach needs to be able to attach a process to specific cgroup, so
cgroup_attach is renamed to lxc_cgroup_attach and now also defined in the
header file.
