Subject: [RFC v2 0/2] cgroup: New misc cgroup controller

Hello

This patch series is creating a new misc cgroup controller for limiting
and tracking of resources which are not abstract like other cgroup
controllers.

This controller was initially proposed as encryption_id but after
the feedbacks, it is now changed to misc cgroup.
https://lore.kernel.org/lkml/20210108012846.4134815-2-vipinsh@google.com/

Changes in RFC v2:
1. Documentation fixes.
2. Added kernel log messages.
3. Changed charge API to treat misc_cg as input parameter.
4. Added helper APIs to get and release references on the cgroup.
