This series contains patches that implement a first version of a generic API to handle RDMA READ/WRITE operations as commonly used on the target (or server) side for storage protocols. This has been developed for the upcoming NVMe over Fabrics target, and extensively teѕted as part of that, although this upstream version has additional updates over the one we're currently using. It hides details such as the use of MRs for iWarp devices, and will allow looking at other HCA specifics easily in the future. This series contains also conversion the SRP and iSER targets to the new API. I think it's basically ready to merge now.

Changes since V6: - rebase to 4.6-rc4 - addressed review comments from Bart on core comments and the srpt wait_list handling - added Reviewed-by: tags from Sagi Changes since V5: - rebase to 4.6-rc3 - now includes signature MR support - now contains the iSER target conversion - new module option for force MR usage for debugging purposes - fixes a bug with the non-merged SG count passes to the MR map routine, causing lockups when using SRP with MRs. - includes the mlx5 max_sg_rd fix (should probably go into 4.6-rc and -stable) Changes since V4: - fix SG iteration in rdma_rw_init_mr_wrs - address various misc review feedback items from Bart and Leon Changes since V3: - really fold the list_del in mr_pool_get into the right patch Changes since V2: - fold the list_del in mr_pool_get into the right patch - clamp the max FR page size length - minor srpt style fix - spelling fixes - renamed rdma_has_read_invalidate to rdma_cap_read_inv Changes since V1: - fixed offset handling in ib_sg_to_pages - uses proper SG iterators to handle larger than PAGE_SIZE segments - adjusted parameters for some functions to reduce size of the context - SRP target support -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
