Hi,
FYI, your patch has been queued to LTS release 17.11.5
Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 12/01/18. So please
shout if anyone has objections.
Also note that after the patch there's a diff of the upstream commit vs the patch applied
to the branch. If the code is different (ie: not only metadata diffs), due for example to
a change in context or macro names, please double check it.
Thanks.
Yongseok

Subject: [PATCH] vhost: remove unneeded null pointer check
[ upstream commit 0541588a44bff07e4aae4c9cde8586326955c378 ]
The caller will guarantee that msg won't be null. Remove
the unneeded null pointer check which caused a Coverity
warning.
