From 725f22a1477c9c15aa67ad3af96fe28ec4fe72d2 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Fri, 13 May 2022 10:13:07 -0700 Subject: block/mq-deadline: Set the fifo_time member also if inserting at head Before commit 322cff70d46c the fifo_time member of requests on a dispatch list was not used. Commit 322cff70d46c introduces code that reads the fifo_time member of requests on dispatch lists. Hence this patch that sets the fifo_time member when adding a request to a dispatch list.
