    Subject[RFC 0/2] cgroup: New misc cgroup controller
    From
    Hello,

    This patch is creating a new misc cgroup controller for allocation 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 from the encryption_id controller are:
    1. There are only 3 files misc.{capacity, max, current} for all
    resources compared to each resource having their own 3 files in
    encryption_id cgroup.
    2. If a resource capacity is 0 then it is considered inactive and won't
    show up in control files.
    2. This is a lockless implementation similar to page counter APIs
    compared to single lock implementation in encryption_id cgroup.

    Please provide any feedback for this RFC or if it is good for
    merging then I can send a patch for merging.

    Thanks
