From a42d985bd5b234da8b61347a78dc3057bf7bb94d Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Fri, 14 Oct 2011 01:30:46 +0000 Subject: ib_srpt: Initial SRP Target merge for v3.3-rc1 This patch adds the kernel module ib_srpt SCSI RDMA Protocol (SRP) target implementation conforming to the SRP r16a specification for the mainline drivers/target infrastructure. This driver was originally developed by Vu Pham and has been optimized by Bart Van Assche and merged into upstream LIO based on his srpt-lio-4.1 branch here: https://github.com/bvanassche/srpt-lio/commits/srpt-lio-4.1/ This updated patch also contains the following two changes from lio-core-2.6.git/master. One is to fix a bug with 1 >= task->task_sg[] chained mappings in ib_srpt, and the other to convert the configfs control plane to reference IB Port GUID and struct srpt_port directly following mainline v4.x target_core_fabric_configfs.c convertion for ib_srpt to work with rtslib/rtsadmin v2 code.
