Thanks for that, though reaching out via bugzilla will probably not
reach the intended audience. Can you actually forward your report to
the following set of addresses:
Ben Skeggs <bskeggs@redhat.com>
Lyude Paul <lyude@redhat.com>
Danilo Krummrich <me@dakr.org>
(from the corresponding commit, plus the following from
get_maintainers.pl output):
Lyude Paul <lyude@redhat.com> (maintainer:DRM DRIVER FOR NVIDIA GEFORCE/QUADRO GPUS)
Danilo Krummrich <dakr@kernel.org> (maintainer:DRM DRIVER FOR NVIDIA GEFORCE/QUADRO GPUS)
Maarten Lankhorst <maarten.lankhorst@linux.intel.com> (maintainer:DRM DRIVERS AND MISC GPU PATCHES)
Maxime Ripard <mripard@kernel.org> (maintainer:DRM DRIVERS AND MISC GPU PATCHES,authored:1/5=20%,added_lines:34/54=63%,removed_lines:34/52=65%)
Thomas Zimmermann <tzimmermann@suse.de> (maintainer:DRM DRIVERS AND MISC GPU PATCHES,commit_signer:2/5=40%)
David Airlie <airlied@gmail.com> (maintainer:DRM DRIVERS)
Simona Vetter <simona@ffwll.ch> (maintainer:DRM DRIVERS,commit_signer:1/5=20%)
and include the following lists as well
dri-devel@lists.freedesktop.org (open list:DRM DRIVER FOR NVIDIA GEFORCE/QUADRO GPUS)
nouveau@lists.freedesktop.org (open list:DRM DRIVER FOR NVIDIA GEFORCE/QUADRO GPUS)
linux-kernel@vger.kernel.org (open list)
Thanks already!
Regards,
Salvatore
