| rwsem-spinlock.c: In function `__rwsem_wake_one_writer':
| rwsem-spinlock.c:111: `tsk' undeclared (first use in this function)
| rwsem-spinlock.c:111: (Each undeclared identifier is reported only once
| rwsem-spinlock.c:111: for each function it appears in.)

How can this ever compile on any architecture?

| static inline struct rw_semaphore *__rwsem_wake_one_writer(struct rw_semaphore *sem)
| {
| 	struct rwsem_waiter *waiter;
|
| 	sem->activity = -1;
|
| 	waiter = list_entry(sem->wait_list.next,struct rwsem_waiter,list);
| 	list_del(&waiter->list);
|
| 	tsk = waiter->task;
| 	mb();
| 	waiter->task = NULL;
| 	wake_up_process(tsk);
| 	free_task_struct(tsk);
| 	return sem;
| }

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
