From 3cf7b233ffc45d4fc381221f74d24f10e692c4ea Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Wed, 21 May 2008 15:54:17 -0500 Subject: [SCSI] libiscsi: fix cmds_max setting Drivers expect that the cmds_max value they pass to the iscsi layer is the max scsi commands + mgmt tasks. This patch implements that and fixes some checks for nr cmd limits.
