From 0df0bb080aca8b3d0f06d9e7d04b07e9ff755ab1 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 29 May 2018 15:52:33 +0200 Subject: [PATCH] null_blk: complete requests from ->timeout By completing the request entirely in the driver we can remove the BLK_EH_HANDLED return value and thus the split responsibility between the driver and the block layer that has been causing trouble.
