[GIT PULL] cgroup changes for v5.13-rc1

From: Tejun Heo
Date: Tue Apr 27 2021 - 10:56:22 EST


Hello, Linus.

The only notable change is Vipin's new misc cgroup controller. This
implements generic support for resources which can be controlled by simply
counting and limiting the number of resource instances - ie. there's X
number of these on the system and this cgroup subtree can have upto Y of
those. The first user is the address space IDs used for virtual machine
memory encryption and expected future usages are similar - niche hardware
features with concrete resource limits and simple usage models.

Thanks.
