From: "Paul E. McKenney" paulmck@kernel.org
The srcu_read_unlock_lite() and srcu_read_unlock_nmisafe() both say that their idx parameters must come from srcu_read_lock(). This would be bad, because a given srcu_struct structure may be used only with one flavor of SRCU reader. This commit therefore updates the srcu_read_unlock_lite() kernel-doc header to say that its idx parameter must be obtained from srcu_read_lock_lite() and the srcu_read_unlock_nmisafe() kernel-doc header to say that its idx parameter must be obtained from srcu_read_lock_nmisafe().
