Hi Nic, Dan,

I’m away this weekend so I can’t test these for a few days at least, unfortunately. I must admit I only vaguely follow the changes here as I haven’t been keeping up with the pace of change in target-devel lately, but it generally looks OK I think.

Are these in linux-next or another branch somewhere I can easily clone them from?

How soon do you need my ACK/NAK on these?

Cheers,
Chris
