From fee099b278894a1c7383a08cb3c62a5b62a134e8 Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Tue, 12 Jan 2010 22:48:00 -0600 Subject: [PATCH] [SCSI] iscsi_tcp regression: remove bogus warn on in write path An empty r2tqueue is a valid state. It just means that we have processed all that there was to do. This patch removes the WARN_ON that was added when the kfifo changes were merged.
