Hi...
Sorry if my earlier post confused some people. What I wanted to say
was actually that spinlock is SMP safe, however, in multicore it makes
code running on a cpu might spin to wait for other code running on
different cpu.
so, to avoid this, perhaps the original poster could gain better

In my opinion,i think spin lock is used for shot-time lock,if you lock
long term, cpu will miss the interrupts, i also have the question
about when we disable local interrupts,can the interrupt be delivered
to other cpus in SMP system?
