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 Signed-off-by: Miaohe Lin <linmiaohe@xxxxxxxxxx> --- kernel/cgroup/cgroup-v1.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/kernel/cgroup/cgroup-v1.c b/kernel/cgroup/cgroup-v1.c index aeef06c465ef..916871babeea 100644 --- a/kernel/cgroup/cgroup-v1.c +++ b/kernel/cgroup/cgroup-v1.c @@ -677,7 +677,7 @@ int proc_cgroupstats_show(struct seq_file *m, void *v) */ for_each_subsys(ss, i) - seq_printf(m, "%s\t%d\t%d\t%d\n", + seq_printf(m, "%-12s\t%-9d\t%-11d\t%-7d\n", ss->legacy_name, ss->root->hierarchy_id, atomic_read(&ss->root->nr_cgrps), cgroup_ssid_enabled(i)); -- 2.27.0
