Only functional test at this point. I'm buliding NUMA awareness to
workqueue and planning on doing comparison of before-wq, after-wq,
after-wq-with-NUMA-awareness. I don't expect any tangible difference
between before-wq and after-wq tho. It would be great if someone can
recommend me a test scenario which can emphasize CPU overhead of
writeback tasks. Any ideas?

Thanks.
