From: "Paul E. McKenney" <[email protected]> Currently, rcu_tasks_initiate_self_tests() prints a message and then initiates self tests on up to three different RCU Tasks flavors. If one of the flavors has a grace-period hang, it is not easy to work out which of the three hung. This commit therefore prints a message prior to each individual test.
