It's late but here are two bug fixes. Both fix problems which can be severe
but are very confined in scope. The risk to most use cases should be
minimal.
* Fix for an old bug which triggers if a cgroup subsystem is remounted to a
different hierarchy while someone is reading its cgroup.procs/tasks file.
The risk is pretty low given how seldom cgroup subsystems are moved across
hierarchies.
* We moved cpus_read_lock() outside of cgroup internal locks a while ago but
forgot to update the legacy_freezer leading to lockdep triggers. Fixed.

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.
