- Plug a task struct reference leak in the percpu rswem implementation.
- Document the refcount interaction with PID_MAX_LIMIT
- Improve the 'invalid wait context' data dump in lockdep so it contains
all information which is required to decode the problem

Pull locking fixes from Thomas Gleixner:
"Three small fixes/updates for the locking core code:
- Plug a task struct reference leak in the percpu rswem
implementation.
- Document the refcount interaction with PID_MAX_LIMIT
- Improve the 'invalid wait context' data dump in lockdep so it
contains all information which is required to decode the problem"

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.
