Adding out-of-line, exported wrappers for every single task state is
kind of silly. But it's still a common operation to wait in a certain
state, so having a single function for that makes sense. Kind of like
spin_lock_irqsave and friends.

Maybe this would be better?:

static inline long schedule_timeout_state(long timeout, long state)
return schedule_timeout(timeout);
