Can't see it do that, also, if it were to do that, we'd not be here since having a waiter would then mean no spinners and no starvation etc..
I was having a hard time understanding why on earth you didn't see that. And yes I was also wondering why it was even there... but I was looking at -next, where we have Ding's original patch b9ce3647b4901071b0dd35d62954a4bb0e5ba1d1.... Paul, could you drop this patch? But yeah, I do agree that waiters should also do the mutex_can_spin_on_owner() check unless I'm missing something subtle from Waiman. Thanks, Davidlohr
