From 1d64508810d8d15867251c75a68d7250278ce2bd Mon Sep 17 00:00:00 2001 From: Hannes Reinecke <hare@suse.de> Date: Thu, 17 Mar 2016 08:39:45 +0100 Subject: scsi: disable automatic target scan On larger installations it is useful to disable automatic LUN scanning, and only add the required LUNs via udev rules. This can speed up bootup dramatically. This patch introduces a new scan module parameter value 'manual', which works like 'none', but can be overridden by setting the 'rescan' value from scsi_scan_target to 'SCSI_SCAN_MANUAL'. And it updates all relevant callers to set the 'rescan' value to 'SCSI_SCAN_MANUAL' if invoked via the 'scan' option in sysfs. Signed-off-by: Hannes Reinecke <hare@suse.de> Reviewed-by: Ewan D.
