From e28f3d5b51ed07d822f135cd941b01e2d485270e Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Thu, 5 Mar 2009 14:46:01 -0600 Subject: [SCSI] libiscsi: don't cap queue depth in iscsi modules There is no need to cap the queue depth in the modules. We set this in userspace and can do that there. For performance testing with ram based targets, this is helpful since we can have very high queue depths.
