[PATCH -mm 0/6] cgroup: block device i/o controller (v11)

[Gui Jianfeng]

Hi Andrea,

I'v tested io-throttle(v11), it seems io-throttle doesn't work well 
when a process writes(delay-write) a small file(<50M may be). it can't 
throttle the request process accurately.
I guess the following reason causes this problem.
The write-request process terminates too early to see all accounting
calculated in pdflush. So io-throttle can't throttle
enough time for that process. Am i right?
