From 766dbb179d41d6337fed2b3ca00caa5845d298ce Mon Sep 17 00:00:00 2001 From: Sagi Grimberg Date: Sun, 6 Nov 2016 11:09:49 +0200 Subject: [PATCH] nvmet-rdma: don't forget to delete a queue from the list of connection failed In case we accepted a queue connection and it failed, we might not remove the queue from the list until we unload and clean it up. We should delete it from the queue list on the relevant handler.
