[dm-devel] [PATCH v4 0/7] per-cpu in_flight counters for bio-based drivers

[Mike Snitzer]

Hey,

This v4 addresses the compile issues on various archs when CONFIG_SMP
isn't set (by introducing appropriate wrappers in genhd.h)

Testing with this v4 I was unable to reproduce the issue you reported
where iostat always reports 0 for avgqu-sz -- but please let me know
if you still see problems like that.

Thanks,
Mike

  dm rq: leverage blk_mq_queue_busy() to check for outstanding IO
  block: stop passing 'cpu' to all percpu stats methods

Mikulas Patocka (5):
  dm: dont rewrite dm_disk(md)->part0.in_flight
  block: delete part_round_stats and switch to less precise counting
  block: switch to per-cpu in-flight counters
  block: return just one value from part_in_flight
  dm: remove the pending IO accounting
