Alexander Lobakin says: ==================== gro: micro-optimize dev_gro_receive() This random series addresses some of suboptimal constructions used in the main GRO entry point. The main body is gro_list_prepare() simplification and pointer usage optimization in dev_gro_receive() itself. Being mostly cosmetic, it gives like +10 Mbps on my setup to both TCP and UDP (both single- and multi-flow). Since v1 [0]: - drop the replacement of bucket index calculation with reciprocal_scale() since it makes absolutely no sense (Eric); - improve stack usage in dev_gro_receive() (Eric); - reverse the order of patches to avoid changes superseding.

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.
