Well, the profile I posted was an interactive UP workload, and it's fairly high there. Trimming cycles off this is good for everyone.
Small SMP boxen (dual?) used similarly will probably see additional gains as the number of locked operations in fget() will be reduced. There's clearly no contention or cacheline bouncing in my workloads as none of them have tasks sharing file tables, nor is anything else messing with the cachelines.
