Re: [libvirt] [PATCH 2/5] vircgroup: Try harder to kill cgroup

Prior to rewrite of cgroup code we only had one backend to try. After the rewrite the virCgroupBackendGetAll() returns both backends (for v1 and v2). However, not both have to really be present on the system which results in killRecursive callback failing which in turn might mean we won't try the other backend. At the same time, this function reports no error as it should. Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com&gt;
