scftorture: Count reschedule IPIs
Currently, only those IPIs that invoke scftorture's scf_handler() IPI handler function are counted. This means that runs exercising only scftorture.weight_resched will look like they have made no forward progress, resulting in "GP HANG" complaints from the rcutorture scripting. This commit therefore increments the scf_invoked_count per-CPU counter immediately after calling resched_cpu(). Fixes: 1ac78b49 ("scftorture: Add an alternative IPI vector") Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
