Mixing different flavors of RCU readers is forbidden, for example, you should not use srcu_read_lock() and srcu_read_lock_nmisafe() on the same srcu_struct structure. There are checks for this, but these checks are not tested on a regular basis. This commit therefore adds such tests to srcu_lockdep.sh. Signed-off-by: Paul E.
