Subject: [PATCH 0/3] Improve mq-deadline I/O priority support
Date: Mon,  4 Dec 2023 21:32:10 -0800	[thread overview]
Message-ID: <20231205053213.522772-1-bvanassche@acm.org> (raw)

Hi Jens,

This patch series includes the following changes for the mq-deadline I/O
scheduler:
 - Do not modify the request order if prio_aging_expire is zero. This
   change restores compatibility of the mq-deadline scheduler with MMC
   devices if prio_aging_expire is set to zero.
 - Ignore I/O priorities for zoned writes that are not write append
   operations such that zoned writes happen in LBA order per zone even
   if different write requests have different I/O priorities in a single
   zone.

Please consider these patches for the next merge window.

Thanks,

Bart.

  block/mq-deadline: Disable I/O prioritization in certain cases
