From 4ba09f69e20d0a768d91277847ddbd31f476590e Mon Sep 17 00:00:00 2001 From: Jens Axboe <axboe@kernel.dk> Date: Mon, 10 Dec 2018 14:45:19 -0700 Subject: [PATCH] mtip32xx: use BLK_STS_DEV_RESOURCE for device resources For cases where we can only fail with IO in-flight, we should be using BLK_STS_DEV_RESOURCE instead of BLK_STS_RESOURCE. The latter refers to system wide resource constraints.
