McKenney <paulmck@xxxxxxxxxxxxxxxxxx> CommitDate: Wed, 27 May 2015 12:59:31 -0700 rcutorture: Test both RCU-sched and RCU-bh for Tiny RCU Tiny RCU supports both RCU-sched and RCU-bh, but only RCU-sched is currently tested by the rcutorture scripts. This commit therefore changes the TINY02 configuration to test RCU-bh, with TINY01 continuing to test RCU-sched. This shortcoming of the current rcutorture tests was located by mutation testing by Iftekhar. The idea behind mutation testing is to automatically mutate the code under test. If a given mutant is not caught by testing, this is a hint that the testing might need to be improved, as was the case here. Note that this is only a hint because it is possible to mutate the code into something else that still works. For example, a mutation that removes (say) a WARN_ON() will not normally result in a test failure. This change resulted in the test failure caused by list mishandling, which is fixed by the next commit. Reported-by: "Ahmed, Iftekhar" <ahmedi@xxxxxxxxxxxxxxxxxxxx> Signed-off-by: Paul E.
