The existing helper test_range_bit works in two ways, checks if the whole range contains all the bits, or stop on the first occurrence. By adding a specific helper for the latter case, the inner loop can be simplified and contains fewer conditionals, making it a bit faster. There's no caller that uses the cached state pointer so this reduces the argument count further. Signed-off-by: David Sterba <dsterba@suse.com>
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.
