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.

====================
Convert rhashtable to use bitlocks
This series converts rhashtable to use a per-bucket bitlock
rather than a separate array of spinlocks.
This:
reduces memory usage
results in slightly fewer memory accesses
slightly improves parallelism
makes a configuration option unnecessary
The main change from previous version is to use a distinct type for
the pointer in the bucket which has a bit-lock in it. This
helped find two places where rht_ptr() was missed, one
in rhashtable_free_and_destroy() in print_ht in the test code.
