On a single core machine - you'll have locked up your entire computer. On a multi-core machine you'll have locked up one core. You don't need to use the spinlock, just disabling interrupts is sufficient. Even on a multicore machine, the spinlocks would just prevent a second core from executing the code if it tried to acquire the same spinlock. I don't think that there is any convenient way to kill such a thread. -- Dave Hylands Shuswap, BC, Canada http://www.davehylands.com _______________________________________________ Kernelnewbies mailing list [email protected] http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
