Re: [Patch v3 0/2] cgroup: KVM: New Encryption IDs cgroup controller

[Tejun Heo]

Hello,

Rough take after skimming:

* I don't have an overall objection. In terms of behavior, the only thing
  which stood out was input rejection depending on the current usage. The
  preferred way of handling that is rejecting future allocations rather than
  failing configuration as that makes it impossible e.g. to lower limit and
  drain existing usages from outside the container.

* However, the boilerplate to usefulness ratio doesn't look too good and I
  wonder whether what we should do is adding a generic "misc" controller
  which can host this sort of static hierarchical counting. I'll think more
  on it.

Thanks.
