This patch is intended as a proof-of-concept for the new SBRM machinery[1]. For some brief background, the idea behind SBRM is using the __cleanup__ attribute to automatically unlock locks (or otherwise release resources) when they go out of scope, similar to C++ style RAII. This promises some benefits such as making code simpler (particularly where you have lots of goto fail; type constructs) as well as reducing the surface area for certain kinds of bugs. The changes in this patch should not result in any difference in how the code actually runs (i.e., it's purely an exercise in this new syntax sugar). In one instance SBRM was not appropriate, so I left that part alone, but all other locking/unlocking is handled automatically in this patch.

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.
