From e0546fc1ba66c90cb38a5764357366267d3e58e4 Mon Sep 17 00:00:00 2001 From: Sagi Grimberg Date: Tue, 10 Jun 2014 13:41:41 +0300 Subject: [PATCH] Target/iser: Fix a wrong dereference in case discovery session is over iser In case the discovery session is carried over iser, we can't access the assumed network portal since the default portal is used. In this case we don't really need to allocate the fastreg pool, just prepare to the text pdu that will follow.
