[dpdk-stable] patch 'examples/eventdev: fix build with gcc 10' has been queued to LTS release 18.11.9

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/03/20. 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.

Queued patches are on a temporary branch at:
https://github.com/kevintraynor/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable-queue/commit/5973c23a8e2c8f59127ee8588a3c081cde5c717d

Thanks.

Kevin.

Subject: [PATCH] examples/eventdev: fix build with gcc 10

[ upstream commit 78de15bb586ac3d8938512db1977d83815c494f8 ]

GCC 10 defaults to -fno-common, this means a linker error will now be
reported if the same global variable is defined in more than one
compilation unit.

Fixes: 3d1b33e44ae2 ("examples/eventdev: move common data into pipeline common")
