  Just a gentle ping. This patch series has been Acked but I haven’t 
seen it picked up by linux-next.

Do you need anything else from me?

Thanks,

There were no Fixes: or Cc: Stable in your changes to indicate they
need to be applied to the currently RC and stable trees, in which case
it will only be merged to next-next at a later stage.

If that is not correct then lets us know if that needs either a Fixes
or stable tag so I can send a pull request immediately.

I saw that it has already been acked-by, but I don’t see this change in
