From e5eab0170410184fa8c2f1ce61df36969b59b5eb Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 29 May 2018 15:52:31 +0200 Subject: [PATCH] nbd: 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.
