Refactor i40e driver to use FIELD_PREP(), which reduces lines of code and adds clarity of intent. This code was generated by the following coccinelle/spatch script and then manually repaired. Refactor one function with multiple if's to return quickly to make lines fit in 80 columns. @prep2@ constant shift,mask; type T; expression a; @@ -(((T)(a) << shift) & mask) +FIELD_PREP(mask, a) @prep@ constant shift,mask; type T; expression a; @@ -((T)((a) << shift) & mask) +FIELD_PREP(mask, a) Cc: Julia Lawall <Julia.Lawall@inria.fr> Reviewed-by: Marcin Szycik <marcin.szycik@linux.intel.com> Reviewed-by: Simon Horman <horms@kernel.org> Signed-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com> Tested-by: Pucha Himasekhar Reddy <himasekharx.reddy.pucha@intel.com> (A Contingent worker at Intel) Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.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.
