The access to logged_impl_name is technically a data race, which tools like KCSAN could complain about in the future. See: https://github.com/google/ktsan/wiki/READ_ONCE-and-WRITE_ONCE Fix by using xchg(), which also ensures that only one thread does the logging. This also required switching from bool to int, to avoid a build error on the RISC-V architecture which doesn't implement xchg on bytes. Signed-off-by: Eric Biggers <ebiggers@google.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.
