There is new patch-status QA check in oe-core: https://git.openembedded.org/openembedded-core/commit/?id=76a685bfcf927593eac67157762a53259089ea8a This is temporary work around just to hide _many_ warnings from optional patch-status (if you add it to WARN_QA). This just added Upstream-Status: Pending everywhere without actually investigating what's the proper status. This is just to hide current QA warnings and to catch new .patch files being added without Upstream-Status, but the number of Pending patches is now terrible: 5 (26%) meta-xfce 6 (50%) meta-perl 15 (42%) meta-webserver 21 (36%) meta-gnome 25 (57%) meta-filesystems 26 (43%) meta-initramfs 45 (45%) meta-python 47 (55%) meta-multimedia 312 (63%) meta-networking 756 (61%) meta-oe Signed-off-by: Martin Jansa <Martin.Jansa@gmail.com> Signed-off-by: Khem Raj <raj.khem@gmail.com>
