Hi,
this is the v3 of the series
https://lkml.org/lkml/2019/3/10/138
that fixes some bug affecting performance, reduces execution time a
little bit, and boosts throughput and responsiveness.

The difference w.r.t. v2 are new fixes to the patch "block, bfq: print
SHARED instead of pid for shared queues in logs", after patient checks
and suggestions by Holger and Oleksandr.

Thanks,
Paolo

Hi Jens,
have you had time to look into this?

Looks ok to me, I'll queue it up for 5.2.
