From 8b1e1244db85d58f7c612870ec2c1afd9098ae93 Mon Sep 17 00:00:00 2001
From: Andy Grover <agrover@redhat.com>
Date: Tue, 3 Apr 2012 15:51:12 -0700
Subject: target/iscsi: Misc cleanups from Agrover (round 2)

This patch includes the handful of squashed patches for target/iscsi from
Andy's original series into lio-core/master code:

*) Make iscsit_add_reject static
*) Remove unused data_offset_end from iscsi_datain_req
*) Remove "#if 0" stubs
*) Rename iscsi_datain_req to cmd_datain_node
*) Cleanups for built_r2ts_for_cmd()
*) Cleanups for Cleanup build_sendtargets_response()
