1 Block IO Controller
6 a need of various kinds of IO control policies (like proportional BW, max BW)
9 and based on user options switch IO policies in the background.
11 Currently two IO control policies are implemented. First one is proportional
14 one is throttling policy which can be used to specify upper IO rate limits
25 - Enable Block IO controller
31 - Compile and boot into kernel and mount IO controller (blkio); see
