[PATCH V5 08/17] blk-throttle: make throtl_slice tunable

2016-12-15 Thread Shaohua Li
throtl_slice is important for blk-throttling. It's called slice internally but it really is a time window blk-throttling samples data. blk-throttling will make decision based on the samplings. An example is bandwidth measurement. A cgroup's bandwidth is measured in the time interval of throtl_slice
