From 14aa7f7eaf8bb1443d043615d8b4827821292204 Mon Sep 17 00:00:00 2001 From: "sreekanth.reddy@lsi.com" Date: Tue, 17 Jul 2012 15:56:13 +0530 Subject: [PATCH] [SCSI] mpt2sas: Fix for With post diag reset same set of device gets added, removed and then again gets added with new target ids When device discovery is disabled during driver load time using module parameter "disable_discovery=1" and when diag reset is issued then from logs, it is observed that the devices get added, removed and then added with new target ids. So, in order to limit this turn-off the code which is deleting and devices across host reset when the disable_discovery module parameter is turned on.
