[PATCH] cgroup-v1: tweak the output format of cgroupstats

[Miaohe Lin]

The output of /proc/cgroups is somewhat awful now. For example, it may
look like below:

subsys_name	hierarchy	num_cgroups	enabled
cpuset	7	95	1
...
perf_event	6	1	1
...
files	10	1	1

Tweak the output format of cgroup stats to make it look better. After
patch applied, it will look like below:

subsys_name	hierarchy	num_cgroups	enabled
cpuset      	11       	73         	1
...
perf_event  	10       	1          	1
...
files       	7        	1          	1
