From 0012fdf986c9b9c7fe8d0842a0ad8dd981a06c06 Mon Sep 17 00:00:00 2001 From: FUJITA Tomonori Date: Thu, 2 Aug 2007 00:20:34 +0900 Subject: [PATCH] [SCSI] scsi_transport_srp: remove tgt dependencies it's better to remove tgt dependencies in srp transport class since most people want only initiator support.
