Subject: [PATCH] cgroup: pretty format /proc/cgroups
Date: Mon, 15 Nov 2021 01:04:07 +0000 [thread overview]
Message-ID: <20211115010407.20380-1-richard.weiyang@gmail.com> (raw)
Current /proc/cgroups looks like this:
cpuset 3 1 1
cpu 2 1 1
cpuacct 2 1 1
memory 4 71 1
freezer 5 1 1
Let's align the title and value. After this patch, it looks like this.
cpuset 5 1 1
cpu 3 1 1
cpuacct 3 1 1
memory 2 71 1
freezer 4 1 1
