patch 'examples/bond: fix invalid use of trylock' has been queued to stable release 21.11.2

[Kevin Traynor <ktraynor@redhat.com>]

Hi,

FYI, your patch has been queued to stable release 21.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/15/22. 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

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/6da5f268db91b8de98626486c84547410ba0fd22

Thanks.

Kevin

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

[ upstream commit 03382cf4115019e6a82d6fca51a16a34a0824a90 ]

The conditional rte_spinlock_trylock() was used as if it is an
unconditional lock operation in a number of places.

Fixes: cc7e8ae84faa ("examples/bond: add example application for link bonding mode 6")
