Suppose that we have a task A, which is holding a spinlock. If A is preempted by task B which try to obtain the same spinlock. Although B has to busy wait, it will end up with be preempted owing to using up its timeslice. Therefore, A has chance to be selected by shechedler and release the spinlock. Then, B will go on when it is selected by the secheduler next time. _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
