we can make them behave like spin lock by disabling the kernel_preemption.

HI
Seems good... But I have one doubt like If I build(or Compile) kernel without kernel preemption. In that case ? What exactly I wants to ask.. this can be the only reason or there can be some thing else?
Inside spinlock implementation, first it disables kernel preemption only when ur kernel built with kernel preemption. (I Read).
