RE: [Infiniband-general] Getting an Infiniband access layer in the linux kernel

We just use the kernel's spin_lock_irqsave(), so I don't know what
you're talking about.

Again, compare them to the current kernel spinlocks and try to realize
why your implementation of spinlock_irqsave() will not work on all
platforms.

Come on, just use the kernel versions, there is no need to reinvent the
wheel all of the time, it just wastes everyones time (including mine...)
