flags & mask are used together everywhere, and are passed around together between multiple functions; they belong together in a struct, call that struct flag_settings. Use struct flag_settings to rework 3 functions: - ddebug_exec_query - declares query and flag-settings, calls other 2, passing flags - ddebug_parse_flags - fills flag_settings and returns - ddebug_change - test all callsites against query, modify passing sites. benefits: - bit-banging always needs flags & mask, best together. - simpler function signatures - 1 less parameter, less stack overhead no functional changes Acked-by: <jbaron@akamai.com> Signed-off-by: Jim Cromie <jim.cromie@gmail.com> Link: https://lore.kernel.org/r/20200719231058.1586423-16-jim.cromie@gmail.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
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.
