rcu: Print human-readable message for schedule() in RCU reader
The WARN_ON_ONCE() invocation within the CONFIG_PREEMPT=y version of rcu_note_context_switch() triggers when there is a voluntary context switch in an RCU read-side critical section, but there is quite a gap between the output of that WARN_ON_ONCE() and this RCU-usage error. This commit therefore converts the WARN_ON_ONCE() to a WARN_ONCE() that explicitly describes the problem in its message. Signed-off-by: Paul E. McKenney <[email protected]>
