memcg: show real limit under hierarchy mode
Show "real" limit of memcg. This helps my debugging and maybe useful for
users.
While testing hierarchy like this
mount -t cgroup none /cgroup -t memory
mkdir /cgroup/A
set use_hierarchy==1 to "A"
mkdir /cgroup/A/01
mkdir /cgroup/A/01/02
mkdir /cgroup/A/01/03
mkdir /cgroup/A/01/03/04
mkdir /cgroup/A/08
mkdir /cgroup/A/08/01
....
and set each own limit to them, "real" limit of each memcg is unclear.
This patch shows real limit by checking all ancestors.
Changelog: (v1) -> (v2)
- remove "if" and use "min(a,b)"
