Hi, Boris.

After working on node balance related code and fs_perf for days, I found that 
current node balancing is not good enough with or without this patch. And I 
come up with a different way to balance the nodes without adding much 
complexity, which will takes me some days to implement and test it. I believe 
it will be much better than the current one if I didn't mess things up.

BTW, I'm not familiar with fs benchmark, so I need some advice about how can I 
get a reasonable benchmark result that can reflect the metadata operation 
performance since I only have a 128G SSD can be used to benchmark, and it's 
speed seems not stable enough. Currently I use kprobe to trace node balance 
related functions to measure if the balance code works well.

Thanks,
Sun YangKai
