From b0c0008148dfc6b2349bc3ce14cda9784002edee Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 6 Nov 2014 15:11:22 -0600 Subject: [PATCH] scsi: call device handler for failed TUR command Multipath devices using the TUR path checker need to see the sense code for a failed TUR command in their device handler. Since commit 1a789310f54502fde057a133ab5b61cce6 we always return success for mid layer issued TUR commands before calling the device handler, which stopped the TUR path checker from working. Move the call to the device handler check sense method before the early return for TUR commands to give the device handler a chance to intercept them.
