From 57339009db54879f240c525a79ef86874a9356a6 Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Mon, 22 Aug 2016 10:54:11 +0200 Subject: [PATCH] target/tcm_fc: use CPU affinity for responses commit 1ba0158fa66b5b2c597a748f87be1650c9960ccc upstream. The libfc stack assigns exchange IDs based on the CPU the request was received on, so we need to send the responses via the same CPU. Otherwise the send logic gets confuses and responses will be delayed, causing exchange timeouts on the initiator side.
