Subject: [PATCH 10/21] target: Convert TMR REQ/RSP definitions to target namespace

From: Nicholas Bellinger <nab@...ux-iscsi.org>

This patch changes include/target/target_core_tmr.h code to use
target specific 'TMR_*' prefixed definitions for fabric independent
SCSI Task Management Request/Request naming in include/scsi/scsi.h
definitions for mainline target code.
