From a144935ceaed277c3e640b85f4cff89d7cce4b8f Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Thu, 6 Feb 2020 05:20:18 -0800 Subject: rcutorture: Set KCSAN Kconfig options to detect more data races 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.
