From e6273993dbcb8d805dd868e2128c3503a3bb1964 Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Tue, 29 Nov 2005 23:12:49 -0600 Subject: [PATCH] [SCSI] iscsi: redirect fix From tomof@acm.org: There is one more issue about Equallogic systems. They send re-direction info with FIN. I think that the kernel module needs to let iscsid to read data from the socket before killing it.
