Subject: [PATCH 0/2] disable I/O priority when prio_aging_expire is zero
Date: Thu, 20 Aug 2026 10:12:44 +0800 [thread overview]
Message-ID: <20260820021246.2681624-1-yebin@huaweicloud.com> (raw)
From: Ye Bin <yebin10@huawei.com>
Since the mq-deadline scheduler introduced support for I/O priorities, if
a process does not have an I/O priority configured, it becomes bound to
the process's scheduling priority. This change forces applications to
re-plan their I/O priorities. However, applications do not care about
I/O priorities, yet now they cannot disable priorities.
Ye Bin (2):
block/mq-deadline: disable I/O priority when prio_aging_expire is zero
block/mq-deadline: add module parameter for prio_aging_expire default
