[PATCH BUGFIX IMPROVEMENT 0/8] block, bfq: fix bugs, reduce exec time and boost performance

[Paolo Valente]

Hi,
since I didn't make it to submit these ones for 5.1, let me be
early for 5.2 :)

These patches fix some bug affecting performance, reduce execution
time a little bit, and boost throughput and responsiveness.

They are meant to be applied on top of the last series I submitted:
https://lkml.org/lkml/2019/1/29/368

Thanks,
Paolo
