2020-06-29torture: Set configfile variable to current scenarioPaul E. McKenney1-0/+1
The torture-test recheck logic fails to set the configfile variable to the current scenario, so this commit properly initializes this variable. This change isn't critical given that all errors for a given scenario follow that scenario's heading, but it is easier on the eyes to repeat it. And this repetition also prevents confusion as to whether a given message goes with the previous heading or the next one. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
2020-06-29rcutorture: Add races with task-exit processingPaul E. McKenney3-3/+128
Several variants of Linux-kernel RCU interact with task-exit processing, including preemptible RCU, Tasks RCU, and Tasks Trace RCU. This commit therefore adds testing of this interaction to rcutorture by adding rcutorture.read_exit_burst and rcutorture.read_exit_delay kernel-boot parameters. These kernel parameters control the frequency and spacing of special read-then-exit kthreads that are spawned. [ paulmck: Apply feedback from Dan Carpenter's static checker. ] [ paulmck: Reduce latency to avoid false-positive shutdown hangs. ] Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
