From 72c0385014a140b6029c5c8bf88efb9ad166ae48 Mon Sep 17 00:00:00 2001 From: Nicholas Bellinger <nab@linux-iscsi.org> Date: Sun, 8 Feb 2015 04:02:08 -0800 Subject: [PATCH] target: Add internal READ_INSERT support This patch adds READ_INSERT support in target_read_prot_action() that invokes sbc_dif_generate() when LIO is responsible for generating the outgoing T10-PI. Required for supporting fabrics that exchange protection information, and would like to function with un-protected devices.
