[ Upstream commit9872916ad1] Newer compiler versions rightfully point out: kernel/kcsan/kcsan_test.c:591:41: error: variable 'dummy' is uninitialized when passed as a const pointer argument here [-Werror,-Wuninitialized-const-pointer] 591 | KCSAN_EXPECT_READ_BARRIER(atomic_read(&dummy), false); | ^~~~~ 1 error generated. Although this particular test does not care about the value stored in the dummy atomic variable, let's silence the warning.

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.
