From 31ed0bf439a15363c28c7a239f52eb127cb6feb3 Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Tue, 26 Feb 2008 12:35:23 -0600 Subject: [PATCH] [SCSI] iscsi regression: check for zero max session cmds The old tools did not set max session cmds. This is a regression. I removed the check when merging the power of 2 patch.
