From c309b35171ddb5384cc3f2f9dc82a96dccc6b7f6 Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Tue, 3 Jun 2014 10:58:52 +0200 Subject: [PATCH] scsi: Remove CONFIG_SCSI_MULTI_LUN Obsolete; either use 'max_lun' if the host supports only a limited number of LUNs or BLIST_NOLUN if the target has problems addressing more than one LUN.
