[dpdk-stable] patch 'build: remove redundant _GNU_SOURCE definitions' has been queued to stable release 20.11.2

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 20.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/12/21. 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/9c3bb2603c1c964ce8fa3740e9d39ac0cf3ff4ce

Thanks.

Subject: [PATCH] build: remove redundant _GNU_SOURCE definitions
Cc: Luca Boccassi <bluca at debian.org>

[ upstream commit e0ae50c6876e899540f6116f8b4f5e5e3dec445f ]

The feature macro _GNU_SOURCE is defined globally,
but there was some remaining useless settings.

The internal definition in config/meson.build is kept,
all other internal definitions of _GNU_SOURCE are removed,
except in examples, which can be built as external applications.
Note: external applications do not inherit of _GNU_SOURCE.

Fixes: 5d7b673d5fd6 ("mk: build with _GNU_SOURCE defined by default")
Fixes: 28188cee2aa0 ("build: enable BSD features visibility for FreeBSD")
Fixes: e6cdc54cc0ef ("net/mlx5: add socket server for external tools")
