Kevin Hao says: ==================== net: Avoid the memory waste in some Ethernet drivers In the current implementation of napi_alloc_frag(), it doesn't have any align guarantee for the returned buffer address. We would have to use some ugly workarounds to make sure that we can get a align buffer address for some Ethernet drivers. This patch series tries to introduce some helper functions to make sure that an align buffer is returned. Then we can drop the ugly workarounds and avoid the unnecessary memory waste. ==================== Link: https://lore.kernel.org/r/20210204105638.1584-1-haokexin@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.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.
