The lock_stress_stats structure's ->n_lock_fail and ->n_lock_acquired fields are incremented and sampled locklessly using plain C-language statements, which KCSAN objects to. This commit therefore marks the statistics gathering with data_race() to flag the intent. While in the area, this commit also reduces the number of accesses to the ->n_lock_acquired field, thus eliminating some possible check/use confusion. Signed-off-by: Paul E.

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.
