Subject: [PATCH] block/mq-deadline: Set the fifo_time member also if inserting at head
Date: Fri, 13 May 2022 10:13:07 -0700 [thread overview]
Message-ID: <20220513171307.32564-1-bvanassche@acm.org> (raw)
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.
