Some issues with CSAN in GCC are 7 years old and one has # been 'fixed' 3 years ago with a half baken solution which 'solved' the # reported issue but not the underlying problem. # # The KCSAN developers also ponder to use a GCC plugin to become # independent, but that's not something which will show up in a few # days. # # Blocking KCSAN until wide spread compiler support is available is not # a really good alternative because the continuous growth of lockless # optimizations in the kernel demands proper tooling support" # # * tag 'locking-kcsan-2020-06-11' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (76 commits) # compiler_types.h, kasan: Use __SANITIZE_ADDRESS__ instead of CONFIG_KASAN to decide inlining #
