From 6e5f0f6383b4896c7e9b943d84b136149d0f45e9 Mon Sep 17 00:00:00 2001 From: Hongyu Jin Date: Wed, 24 Jan 2024 13:35:53 +0800 Subject: dm io: Support IO priority Some IO will dispatch from kworker with different io_context settings than the submitting task, we may need to specify a priority to avoid losing priority. Add IO priority parameter to dm_io() and update all callers.
