The automatic classification engine (cgexec, cgclassify, pam_cgroup)
classify tasks. It is useful for an application to know where it has been classified. I propose to add a new API cgroup_get_current_controller_path() that returns the current classification directory for the specified controller. One can easily add on and build new API that will return paths of all mounted controllers, but I want to start with something simple and useful. I've also added a bunch of test cases for the same purpose. Test output # ./pathtest.sh Test FAIL, get path failed for controller cpuset Test PASS, controller cpu path /default Test PASS, controller cpuacct path /default Test PASS, controller memory path /default Test FAIL, get path failed for controller memrlimit I mounted just cpu, cpuacct and memory, thus the path for cpuset and memrlimit could not be found (as expected).
