Linux Operating System Source Code: IBM Patches

 
scalable kernel statistics (kernel_stat)
Description:
This patch splits out disk statistics from kernel_stat and makes the rest of kernel_stat per-CPU and uses per-CPU data area. This improves scalability for both SMP and NUMA (per-CPU data area will eventually support NUMA-aware allocation). All arch code needs to be modified to support these changes. Also added with this is CPU notifier support for kernel_stat.
