Subject: [PATCH BUGFIX IMPROVEMENT 0/8] block, bfq: fix bugs, reduce exec time and boost performance
Date: Thu, 7 Mar 2019 17:25:46 +0100 [thread overview]
Message-ID: <20190307162554.77205-1-paolo.valente@linaro.org> (raw)
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
