Using --kcsan when the compiler does not support KCSAN results in this: :CONFIG_KCSAN=y: improperly set :CONFIG_KCSAN_REPORT_ONCE_IN_MS=100000: improperly set :CONFIG_KCSAN_VERBOSE=y: improperly set :CONFIG_KCSAN_INTERRUPT_WATCHER=y: improperly set Clean KCSAN run in /home/git/linux-rcu/tools/testing/selftests/rcutorture/res/2020.06.16-09.53.16 This is a bit obtuse, so this commit adds checks resulting in this: :CONFIG_KCSAN=y: improperly set :CONFIG_KCSAN_REPORT_ONCE_IN_MS=100000: improperly set :CONFIG_KCSAN_VERBOSE=y: improperly set :CONFIG_KCSAN_INTERRUPT_WATCHER=y: improperly set Compiler or architecture does not support KCSAN! Did you forget to switch your compiler with --kmake-arg CC=<cc-that-supports-kcsan>? Suggested-by: Marco Elver <elver@google.com> 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.
