Subject: [PATCH 0/2] mq-deadline fixes
Date: Thu, 24 Nov 2022 11:12:06 +0900 [thread overview]
Message-ID: <20221124021208.242541-1-damien.lemoal@opensource.wdc.com> (raw)
A couple of patches to fix (1) a potential problem with mq-deadline IO
priority handling and (2) to improve write performance with HDDs.
While the performance improvement patch is technically not a bug fix,
the improvement is so significant with some HDDs that I added cc-stable
tag to get the patch added to LTS kernels.
Damien Le Moal (2):
block: mq-deadline: Fix dd_finish_request() for zoned devices
block: mq-deadline: Do not break sequential write streams to zoned
HDDs
