of local_lock_t - this primitive comes from the -rt project and identifies CPU-local locking dependencies normally handled opaquely beind preempt_disable() or local_irq_save/disable() critical sections. The generated code on mainline kernels doesn't change as a result, but still there are benefits: improved debugging and better documentation of data structure accesses. The new local_lock_t primitives are introduced and then utilized in a couple of kernel subsystems. No change in functionality is intended. There's also other smaller changes and cleanups.

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.
