Sebastian Andrzej Siewior 512bf713cb lockdep/selftests: Unbalanced migrate_disable() & rcu_read_lock(). ... The tests with unbalanced lock() + unlock() operation leave a modified preemption counter behind which is then reset to its original value after the test. The spin_lock() function on PREEMPT_RT does not include a preempt_disable() statement but migrate_disable() and read_rcu_lock(). As a consequence both counter never get back to their original value and the system explodes later after the selftest. In the double-unlock case on PREEMPT_RT, the migrate_disable() and RCU code will trigger a warning which should be avoided. These counter should not be decremented below their initial value. Save both counters and bring them back to their original value after the test. In the double-unlock case, increment both counter in advance to they become balanced after the double unlock.
