Subject: [dpdk-stable] patch 'raw/ntb: check memory allocations' has been queued to stable release 19.11.9
Date: Mon, 17 May 2021 18:21:15 +0200

Hi,

FYI, your patch has been queued to stable release 19.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/19/21. 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/cpaelzer/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/cpaelzer/dpdk-stable-queue/commit/3ebb07801c117f3807df26fccee4ac6c304c33a1

Thanks.

Christian Ehrhardt <christian.ehrhardt@canonical.com>
