patch 'vdpa/mlx5: fix mkey creation check' has been queued to stable release 20.11.4

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 20.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/30/21. 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/steevenlee/dpdk

This queued commit can be viewed at:
https://github.com/steevenlee/dpdk/commit/bc9ea21f705e5c0b66b9e187e92b24b38fddabfd

Thanks.

Subject: [PATCH] vdpa/mlx5: fix mkey creation check
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit e9511a26e1c4fed566c3c2ea33ca895b7ab4f724 ]

The return value of "mlx5_os_wrapped_mkey_create" is checked in the
caller. A zero means success without any error.

The typo in the if-condition should be fixed in case there is a
misjudgment.

Fixes: 398ea8450c53 ("vdpa/mlx5: workaround dirty bitmap MR creation")
