From 18e9781d44000bcb403941011d954896df7439cc Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Thu, 27 Jul 2017 08:03:57 -0600 Subject: [PATCH] blk-mq: blk_mq_requeue_work() doesn't need to save IRQ flags We know we're in process context, so don't bother using the IRQ safe versions of the spin lock.
