From: Kyungmin Park <[email protected]> Some platform uses freezer cgroup for speicial purpose to schedule out some applications. but after suspend & resume, these processes are thawed and running.
but it's inteneded and don't need to thaw it. To avoid it, does it possible to modify resume code and don't thaw it when resume? does it resonable?
