    blkio: Add io controller stats like · 303a3acb
    Divyesh Shah 提交于
    - io_service_time
    - io_wait_time
    - io_serviced
    - io_service_bytes
    
    These stats are accumulated per operation type helping us to distinguish between
    read and write, and sync and async IO. This patch does not increment any of
    these stats.
