kcsan: Address missing case with KCSAN_REPORT_VALUE_CHANGE_ONLY Even with KCSAN_REPORT_VALUE_CHANGE_ONLY, KCSAN still reports data races between reads and watchpointed writes, even if the writes wrote values already present. This commit causes KCSAN to unconditionally skip reporting in this case. Signed-off-by: Marco Elver <elver@google.com> Signed-off-by: Paul E.
