But that gives a contradiction when n == 0 - we can't show exactly 0 lines for an unbound multi subsys, and still show every subsystem. Does libcgroup actually parse /proc/cgroup? If not, maybe we should just break the format now and replace it with something more extensible for future changes. > And some cgroup test programs, like controller tests in ltp and some > test programs that I wrote, but they are ok for this change. Right, changes to test programs aren't a compatibility issue.
