Pull another cgroup fix from Tejun Heo:
"Commit 4f7e723643 ("cgroup: Fix threadgroup_rwsem <->
cpus_read_lock() deadlock") required the cgroup
core to grab cpus_read_lock() before invoking ->attach().
Unfortunately, it missed adding cpus_read_lock() in
cgroup_attach_task_all(). Fix it"

cgroup: Add missing cpus_read_lock() to cgroup_attach_task_all()
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.
