procfs cgroups string problem

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 The cgroups string returned is built by joining the entries in /proc/PID/cgroup by a comma. Unfortunately, cgroup controller names can contain commas. This make parsing out the cgroups problematic. $ cat /proc/self/cgroup 10:hugetlb:/ 9:perf_event:/ 8:net_cls,net_prio:/ 7:freezer:/ 6:devices:/user.slice 5:memory:/ 4:blkio:/ 3:cpu,cpuacct:/ 2:cpuset:/ 1:name=systemd:/user.slice/user-5160.slice/session-1.scope It looks like anything that is a valid filename can be a controller name. It might be better to return a tuple of entries. - --Guy
