The difference between for_each_cpu() and for_each_set_bit() is that the latter uses cpumask_next() instead of find_next_bit(), and so calls cpumask_check(). This check is useless because the iterator value is not provided by user. It generates false-positives for the very last iteration of for_each_cpu(). Signed-off-by: Yury Norov <yury.norov@gmail.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.
