Hi, Ming! Hi, Christoph! Hi, Bart! Friendly ping ... The 'util' reported by iostat is very important for users, they don't have much choise to get disk status, while 'util' has been inaccurate for a long time unnecessarily. I really think patch 1 is meaningful. Patch 2 also tries to fix a problem by our customer that util can sometimes be huge. The root cause is that 'inflight' is account from blk_mq_start_request() while 'io_ticks' is account from blk_account_io_start(), there is a gap. I let 'inflight' to be account from blk_account_io_start() as well, please let me know if this is not good. Thanks!
