From 7beb2f845b715cb98584cf630e9a9d5b05501166 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Sat, 30 Sep 2017 02:08:24 -0600 Subject: [PATCH] blk-mq: wire up completion notifier for laptop mode For some reason, the laptop mode IO completion notified was never wired up for blk-mq. Ensure that we trigger the callback appropriately, to arm the laptop mode flush timer.
