[dpdk-stable] patch 'app/eventdev: detect deadlock for timer event producer' has been queued to LTS release 18.11.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 01/11/19. 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] app/eventdev: detect deadlock for timer event producer

[ upstream commit 4730378428cf32a8ccdf6c018a399536a7144cc6 ]

If timer events get dropped for some reason, the thread that launched
producer and worker cores will never exit, because the deadlock check
doesn't currently apply to the event timer adapter case. This commit
fixes this.

Fixes: d008f20bce23 ("app/eventdev: add event timer adapter as a producer")
