From: Bart Van Assche Date: Sat, 29 Oct 2016 00:20:49 +0000 (-0700) Subject: blk-mq: Remove blk_mq_cancel_requeue_work() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9b7dd572cc439fa92e120290eb74d0295567c5a0;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git blk-mq: Remove blk_mq_cancel_requeue_work() Since blk_mq_requeue_work() no longer restarts stopped queues canceling requeue work is no longer needed to prevent that a stopped queue would be restarted. Hence remove this function.
