Now 'BPF_MAP_TYPE_PERCPU_CGROUP_STORAGE + local percpu ptr'

I found this commit message very confusing until I realized there was a typo
here. Shouldn't this be "Now 'BPF_MAP_TYPE_CGRP_STORAGE + local percpu ptr'"?

You are right. Thanks for pointing this out. Will fix in the
next revision.


can cover all BPF_MAP_TYPE_PERCPU_CGROUP_STORAGE functionality
and more. So mark BPF_MAP_TYPE_PERCPU_CGROUP_STORAGE deprecated.
