Although the accesses used to determine whether or not a stall should be printed are an integral part of the concurrency algorithm governing use of the corresponding variables, the values that are simply printed are ancillary. As such, it is best to use data_race() for these accesses in order to provide the greatest latitude in the use of KCSAN for the other accesses that are an integral part of the algorithm. This commit therefore changes the relevant uses of READ_ONCE() to data_race(). Signed-off-by: Paul E. McKenney <paulmck@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.
