Hmm... yeah, that does increase the amount of output, but I don't know. The
trade-off is between consistency and brevity and I think I'd go for
consistency here.
prefer just showing those that are enabled. As for dying memory cgroups,
they will only be shown in its online ancestors. We currently don't know how
So, one peculiarity with memory is that when you enable io, it gets
implicitly enabled together and we likely wanna show that.
If memory is implicitly enabled, it is treated as enabled as the
corresponding cgroup->subsys[] entry should be set. I currently don't
filter out those in the cgrp_dfl_implicit_ss_mask. So perf_event, which
is implicitly enabled, is shown in all the cgroup.stat.
If you still want to display all even if some of them are not enabled, I
can certainly do that.
