From: "Paul E. McKenney" <paulmck@xxxxxxxxxx> Currently, the CONFIG_PREEMPT_NONE=y rcutorture TRACE01 rcutorture scenario enables lockdep. This limits its ability to find bugs due to non-preemptible sections of code being RCU readers, and pretty much all code thus appearing to lockdep to be an RCU reader. This commit therefore moves lockdep testing to the CONFIG_PREEMPT=y rcutorture TRACE02 scenario. Signed-off-by: Paul E.
