From: Bart Van Assche <bvanassche@xxxxxxx> (Resending w/o the full body as it's exceeding the patch size limit.. ;) This v3 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 patch has been updated to build against the latest target patches in the queue for v3.2-rc1, and includes the last review feedback as listed in the changelog below. This has been getting some linux-next build testing over the last days, so please have a final look and if there are no objections for an initial merge this version will be sent out in PULL request form for mainline by the end of the week. 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. This patch is made against the current pending target-core changes for v3.2-rc1, the full tree is available here: git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending.git for-next-merge 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.
