[dpdk-stable] patch 'vfio: document multiprocess limitation for container API' has been queued to LTS release 18.11.2

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 04/24/19. 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. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Thanks.

Kevin Traynor

Subject: [PATCH] vfio: document multiprocess limitation for container API

[ upstream commit 1fd3bcf3f97b219a93456466cb1aa46e2419f051 ]

Currently, there is no support for sharing custom VFIO containers
between multiple processes, but it is not documented.

Document this limitation.
