[dpdk-stable] patch 'examples/vhost_blk: fix build with pkg-config' has been queued to stable release 19.11.6

[luca.boccassi at gmail.com]

Hi,

FYI, your patch has been queued to stable release 19.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/19/20. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/882655e21ef763cff199b8b411081dee999779fe

Thanks.

Luca Boccassi

vhost_blk.c: In function ‘ctrlr_worker’:

[-Wimplicit-function-declaration]

      |  ^~~~~~~~~~~~~~~~~~~~~~
/usr/bin/ld: /tmp/cczpiMWH.o: in function `ctrlr_worker':
vhost_blk.c:(.text+0x1076): undefined reference to `CPU_ZERO'

`CPU_SET'
collect2: error: ld returned 1 exit status
gmake: *** [Makefile:34: build/vhost-blk-shared] Error 1

Explicitly pass _GNU_SOURCE and include missing headers (rather than
rely on automagic inclusion from other system headers).

Fixes: c19beb3f38cd ("examples/vhost_blk: introduce vhost storage sample")
