Subject: [PATCH v2 0/3] Improve loop driver I/O scheduler and QD selection
Date: Tue,  3 Aug 2021 11:23:01 -0700	[thread overview]
Message-ID: <20210803182304.365053-1-bvanassche@acm.org> (raw)

Hi Jens,

The two patches in this patch series are what I came up with while testing
Android software. Please consider these patches for inclusion in the upstream
kernel.

Thanks,

Bart.

Changes compared to v1:
- Introduced BLK_MQ_F_NO_SCHED_BY_DEFAULT and use it in the loop driver.
- Removed BLK_MQ_F_NO_SCHED again from the loop driver.

Bart Van Assche (3):
  blk-mq: Introduce the BLK_MQ_F_NO_SCHED_BY_DEFAULT flag
  loop: Select I/O scheduler 'none' from inside add_disk()
  loop: Add the default_queue_depth kernel module parameter
