Linus Torvalds 7716f383a5 cgroup: Changes for v6.6 
* 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 is added. This causes trivial
   conflicts in .gitignore and Makefile under the directory against
   fe3b1bf19b ("selftests: cgroup: add test_zswap program"). They can be
   resolved by keeping lines from both branches.

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
