[dpdk-stable] patch 'fbarray: fix detach in --no-shconf mode' has been queued to stable release 18.08.1

[Kevin Traynor <ktraynor@redhat.com>]

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 11/23/18. 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] fbarray: fix detach in --no-shconf mode

[ upstream commit 310aa7c04143105200fd81ae3e5f680e22c9bb6a ]

In noshconf mode, no shared files are created, but we're still trying
to unlink them, resulting in detach/destroy failure even though it
should have succeeded. Fix it by exiting early in noshconf mode.

Fixes: 3ee2cde248a7 ("fbarray: support --no-shconf mode")
