Hi,

FYI, your patch has been queued to stable release 20.11.8

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/25/23. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/59e1f7e8f3143fe3e90d1a1dd359c198230287f8

Thanks.

Luca Boccassi

Subject: [PATCH] reorder: invalidate buffer from ready queue in drain

[ upstream commit af12092f927d0d230b4dc051529dae88902fba1c ]

Set drained buffers from ready queue to NULL, since their ownership
returned to user. Otherwise it's possible that both user and library
will attempt to free the packet.

Fixes: b70b56032bff ("reorder: new library")
