Hi Sumit,

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
