Alex Elder says: ==================== net: ipa: a mix of small improvements Version 2 of this series restructures a couple of the changed functions (in patches 1 and 2) to avoid blocks of indented code by returning early when possible, as suggested by Jakub. The description of the first patch was changed as a result, to better reflect what the updated patch does. It also fixes one spot I identified when updating the code, where gsi_channel_stop() was doing the wrong thing on error. The original description for this series is below. This series contains a sort of unrelated set of code cleanups. The first two are things I wanted to do in a series that updated some NAPI code recently. I didn't want to change things in a way that affected existing testing so I set these aside for later (i.e., now). The third makes a change to event ring handling that's similar to what was done a while back for channels. There's little benefit to cacheing the current state of an event ring, so with this we'll just fetch the state from hardware whenever we need it. The fourth patch removes the definitions of two unused symbols. The fifth replaces a count that is always 0 or 1 with a Boolean. The sixth removes a build-time validation check that doesn't really provide benefit. And the last one fixes a problem (in two spots) that could cause a build-time check to fail "bogusly". ==================== Link: https://lore.kernel.org/r/20210205221100.1738-1-elder@linaro.org 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.
