IS_ERR(), IS_ERR_OR_NULL(), IS_ERR_VALUE() and WARN*() already contain unlikely() optimization internally. Thus, there is no point in calling these functions and defines under likely()/unlikely(). This check is based on the coccinelle rule developed by Enrico Weigelt https://lore.kernel.org/lkml/1559767582-11081-1-git-send-email-info@metux.net/ Link: http://lkml.kernel.org/r/20190829165025.15750-1-efremov@linux.com Signed-off-by: Denis Efremov <efremov@linux.com> Cc: Joe Perches <joe@perches.com> Cc: Alexander Viro <viro@zeniv.linux.org.uk> Cc: Anton Altaparmakov <anton@tuxera.com> Cc: Boris Ostrovsky <boris.ostrovsky@oracle.com> Cc: Boris Pismenny <borisp@mellanox.com> Cc: Darrick J.

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.
