Jani, would it make sense to cherry-pick this to -fixes? The
offending
commit is in drm-next, and there have been a few reports
around this.

Fixes: a035154da45d ("drm/i915/dmabuf: add paranoid flush-on-
acquire")

If the Fixes: tag is in place, our tooling will cherry-pick it
where it
belongs. (In this case, drm-intel-next-fixes, not drm-intel-
fixes.)

Yeah, I forgot to add the fixes tag here unfortunately.

Already merged? What's the commit id to be cherry-picked? Rodrigo
can do
it manually.

Yeah, it was merged to gt-next:

777226dac058 ("drm/i915/dmabuf: fix broken build")

picked up to drm-intel-next-fixes

Thanks.

Hmm it looks like we have this in -fixes (and in -gt) while Linus has explicitly thrown it out (see https://lists.freedesktop.org/archives/dri-devel/2021-November/330928.html).

End result is that now we have a different Kernel Test Robot warning ("asm/smp.h is included more than once.").

So we need to fish out "drm/i915/dmabuf: fix broken build" out from fixes with a revert or what?

Regards,

Tvrtko



thanks,
Rodrigo.



Note to self, we should set up some way to check which maintainer
is
responsible for which branches and when.

BR,
Jani.



Cc: Rodrigo who covers drm-intel-next-fixes atm.

BR,
Jani.
