Hi, Jens!
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.
Friendly ping ...
Thanks!
