[dpdk-stable] patch 'lib: fix unnecessary double negation' has been queued to LTS release 18.11.7

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/25/20. 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-queue

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable-queue/commit/368b63ca65b313dde4e85d85ea5a926914c4b207

Thanks.

Kevin.

Subject: [PATCH] lib: fix unnecessary double negation

[ upstream commit f42c9ac5b6b5fabd3c6bb124914af6704445e853 ]

An equality expression already returns either 0 or 1.
There is no need to use double negation for these cases.

Fixes: ea672a8b1655 ("mbuf: remove the rte_pktmbuf structure")
Fixes: a0fd91cefcc0 ("mempool: rename functions with confusing names")
