[0/2] fixes for block stats

Message

Hou Tao May 21, 2019, 7:59 a.m. UTC

The first patch fixes the problem that there is no sample in
/sys/kernel/debug/block/nvmeXn1/poll_stat and hybrid poll may
don't work as expected. The second patch tries to ensure
the latency accounting for block stats will work normally
even when iostat is disabled.

Comments are wecome.

Regard,
Tao

Hou Tao (2):
  block: make rq sector size accessible for block stats
  block: also check RQF_STATS in blk_mq_need_time_stamp()
