From: "Paul E. McKenney" <paulmck@xxxxxxxxxx> This commit enables the KCSAN Kconfig options that (1) detect data races between reads and writes even when the writes do not change the variable's value and (2) detect data races involving plain C-language writes. These changes only affect scripted rcutorture runs and can be overridden using the kvm.sh --kconfig argument. Signed-off-by: Paul E.
