Subject: [dpdk-dev] [PATCH v2 03/17] vhost: fix error handling when mem table gets updated
Date: Tue, 2 Oct 2018 11:36:37 +0200 [thread overview]
Message-ID: <20181002093651.24795-4-maxime.coquelin@redhat.com> (raw)
In-Reply-To: <20181002093651.24795-1-maxime.coquelin@redhat.com>
When the memory table gets updated, the rings addresses need
to be translated again. If it fails, we need to exit cleanly
by unmapping memory regions.
Fixes: d5022533c20a ("vhost: retranslate vring addr when memory table changes")
