* o He gets the write lock.
* o Interupts are still enabled, we take an interrupt with the
* write still holding the lock.
* o interrupt handler tries to acquire the rwlock for read.
* o deadlock since the writer can't release it at this point.
*
* In general, any use of spinlocks that competes between "base"
* level and interrupt level code will risk deadlock. Interrupts
* need to be disabled in the base level routines to avoid it.
* Or more precisely, only the IRQ the base level routine
* is competing with for the lock. But it's more efficient/faster
* to just disable all interrupts on that CPU to guarantee
* once it gets the lock it can release it quickly too.
