From 7e85c91970125cb16399c7d1cfedc943266eee49 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Mon, 10 Aug 2015 17:06:57 -0700 Subject: [PATCH] IB/srp: Use multiple registrations for large memory regions Instead of using the global rkey for large memory regions, use multiple registrations. See also the while (dma_len) loop further down in srp_map_sg_entry().
