Currently, rcu_torture_writer() checks only for rcu_gp_is_expedited() when deciding whether or not to do dynamic control of RCU expediting. This means that if rcupdate.rcu_normal is specified, rcu_torture_writer() will attempt to dynamically control RCU expediting, but will nonetheless only test normal RCU grace periods. This commit therefore adds a check for !rcu_gp_is_normal(), and prints a message and desists from testing dynamic control of RCU expediting when doing so is futile. Signed-off-by: NPaul E.
