Hi,

I've read that on single-processor machines rather than holding a spinlock,
the kernel disables kernel preemption (2.6). However, it seems that
interrupts are still enabled so if an interrupt occured and call the
function who is suposed to contain the spinlock, we will have data
consistency problem since the function who has been interrupted was doing
something in the critical region and the isr is doing something in the
critical region too. Someone can explain me what I dont understand?

Thank you
