Subject: [Patch v3 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 v3:
1. Changed implementation to support 64 bit counters.
2. Print kernel logs only once per resource per cgroup.
3. Capacity can be set less than the current usage.

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.
