+From: James Smart <james.smart@emulex.com>
+Subject: add missing interim SDEV_DEL state if slave_alloc fails
+References: bnc#468640
+
+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.
