Subject: [PATCH BUGFIX IMPROVEMENT V3 0/1] block, bfq: eliminate latency regression with fast drives
Date: Thu, 18 Jul 2019 09:08:51 +0200	[thread overview]
Message-ID: <20190718070852.34568-1-paolo.valente@linaro.org> (raw)

[V3 that mentions the fixed/improved commit]

Hi Jens,
I've spotted a regression on a fast SSD: a loss of I/O-latency control
with interactive tasks (such as the application start up I usually
test). Details in the commit.

I do hope that, after proper review, this commit makes it for 5.3.

Thanks,
Paolo
