From dfd402a4c4baae42398ce9180ff424d589b8bffc Mon Sep 17 00:00:00 2001 From: Marco Elver Date: Thu, 14 Nov 2019 19:02:54 +0100 Subject: kcsan: Add Kernel Concurrency Sanitizer infrastructure Kernel Concurrency Sanitizer (KCSAN) is a dynamic data-race detector for kernel space. KCSAN is a sampling watchpoint-based data-race detector. See the included Documentation/dev-tools/kcsan.rst for more details. This patch adds basic infrastructure, but does not yet enable KCSAN for any architecture. Signed-off-by: Marco Elver Acked-by: Paul E. McKenney Signed-off-by: Paul E.
