would now create a variable called per_cpu_offset__myint in the .data.percpu_offset section. This variable will point to the (if defined in the kernel) __per_cpu_offset[] array. If this was a module variable, it would point to the module per_cpu_offset[] array which is created when the modules is loaded.
If I'm following you correctly, this adds another dependent load to a per-CPU data access, and from memory that isn't node-affine. If so, I think people with SMP and NUMA kernels would care more about performance and scalability than the few k of memory this saves. -- SUSE Labs, Novell Inc.Send instant messages to your online friends http://au.messenger.yahoo.com -
