Subject: [PATCH] [BZ 192049] udev/dasd: change DASD udev-rule to set none
scheduler
From: Stefan Haberland <s...@linux.ibm.com>
Description: dasd: change default scheduler to reduce CPU consumption
Symptom: CPU consumption up to 20% higher for mq-deadline
compared to none scheduler for DASD devices with no
difference in throughput.
Problem: Performance analysis showed that with recent DASD
device drivers using multi-queue block queuing the
throughput of mq-deadline and none scheduler is nearly
identical but the CPU consumption of mq-deadline
scheduler due to its optimizations is up to 20% higher
compared to none scheduler.
Solution: Set none scheduler as default in the DASD udev rule.
Reproduction: Use DASD devices with mq-deadline scheduler.

Problem-ID: 192049
Upstream-Description:
udev/dasd: change DASD udev-rule to set none scheduler
Performance evaluation showed that using the mq-deadline
scheduler for DASD
devices leads to a significantly higher CPU consumption compared
to using
none scheduler while having the same amount of throughput.
Setting none scheduler as default in the dasd udev rule.
