[dpdk-stable] patch 'efd: fix write unlock during ring creation' has been queued to stable release 18.08.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 18.08.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 12/08/18. 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.

Kevin Traynor

Subject: [PATCH] efd: fix write unlock during ring creation

[ upstream commit f493119397d0f5dbe33f67697ff09aa646e5f17c ]

In rte_efd_create() write lock has already been unlocked
before ring creation itself.
So second unlock after the ring creation has been removed.

Fixes: 56b6ef874f80 ("efd: new Elastic Flow Distributor library")
