This series replaces all the open-coded integer division and multiplication conversions between rt blocks and rt extents with calls to static inline helpers. Having cleaned all that up, the helpers are augmented to skip the expensive operations in favor of bit shifts and masking if the rt extent size is a power of two. v1.1: various cleanups suggested by hch With a bit of luck, this should all go splendidly.

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.
