Subject: [PATCH FIXES/IMPROVEMENTS 0/7] block, bfq: preserve control, boost throughput, fix bugs
Date: Sat, 19 Jun 2021 16:09:41 +0200	[thread overview]
Message-ID: <20210619140948.98712-1-paolo.valente@linaro.org> (raw)

Hi Jens,
this series contains an already proposed patch by Luca, plus six new
patches. The goals of these patches are summarized in the subject of
this cover letter. I'm including Luca's patch here, because it enabled
the actual use of stable merge, and, as such, triggered an otherwise
silent bug. This series contains also the fix for that bug ("block,
bfq: avoid delayed merge of async queues"), tested by Holger [1].

Thanks,
Paolo
