Did that patch cause any issue, or is it just not needed on your system?
It fixes an hypothetical problem with the way ATS is implemented. Maybe I
actually observed it on an old software model, I don't remember. Either
way it's unlikely to go upstream but I'd like to know if I should drop it
from my tree.

Thanks,
Jean
