From c2f9e49f9bbfa2e111ab1e1628b96b560bae7cec Mon Sep 17 00:00:00 2001 From: James Smart Date: Tue, 27 Jan 2009 11:41:36 -0500 Subject: [PATCH] [SCSI] scsi_scan: add missing interim SDEV_DEL state if slave_alloc fails We were running i/o and performing a bunch of hba resets in a loop. This forces a lot of target removes and then rescans. Since the resets are occuring during scan it's causing the scan i/o to timeout, invoking error recovery, etc. We end up getting some nasty crashing in scsi_scan.c due to references to old sdevs that are failing but had some lingering references that kept them around. Fix by setting device state to SDEV_DEL if the LLD's slave_alloc fails.
