Pull cgroup updates from Tejun Heo:

- Per-cpu cpu usage stats are now tracked

This currently isn't printed out in the cgroupfs interface and can
only be accessed through e.g. BPF. Should decide on a not-too-ugly
way to show per-cpu stats in cgroupfs

- cpuset received some cleanups and prepatory patches for the pending
cpus.exclusive patchset which will allow cpuset partitions to be
created below non-partition parents, which should ease the management
of partition cpusets

- A lot of code and documentation cleanup patches

- tools/testing/selftests/cgroup/test_cpuset.c added

Pull cgroup updates from Tejun Heo:

- Whenever cpuset needs to rebuild sched_domain, it walked all tasks
looking for DEADLINE tasks as they need to be accounted on the new
domain. Walking all tasks can be expensive and there may not be any
DEADLINE tasks at all. Task iteration is now omitted if there are no
DEADLINE tasks

- Fixes DEADLINE bandwidth misaccounting after task migration failures

- When no controller is enabled, -Wstringop-overflow warning is
triggered. The fix patch added an early exit which is too eager and
got reverted for now. Will fix later

- Everything else is minor cleanups

cgroup/misc: Expose misc.current on cgroup v2 root

Hello,

This patch is to expose misc.current on cgroup v2 root for tracking
how much of the resource has been consumed in total on the system.

Most of the cloud infrastucture use cgroup to fetch the host
information for scheduling purpose.

Currently, the misc controller can be used by Intel TDX HKIDs and
AMD SEV ASIDs, which are both used for creating encrypted VMs.
Intel TDX and AMD SEV are mostly be used by the cloud providers
for providing confidential VMs.

In actual use of a server, these confidential VMs may be launched
in different ways. For the cloud solution, there are kubvirt and
coco (tracked by kubepods.slice); on host, they can be booted
directly through qemu by end user (tracked by user.slice), etc.

In this complex environment, when wanting to know how many resource
is used in total it has to iterate through all existing slices to
get the value of each misc.current and add them up to calculate
the total number of consumed keys.

So exposing misc.current to root cgroup tends to give much easier
when calculates how much resource has been used in total, which
helps to schedule and count resources for the cloud infrastucture.

In scenarios where containers are frequently created and deleted,

resource request failed. As misc.events has provided relevant
information, maybe we can remove this log.
