SubjectRe: spin_lock and linux philosophy question...

But that brings up a larger question of why there are spin
locks at all? If a CPU can't be doing one thing because a
particular resource is unavailable being used by another CPU, why
isn't it then sent off to do something else?

Please read "Unix Systems for Modern Architectures" by Curt Schimmel
for a good primer on spinlocks and why they are used in an OS.
