As more drivers start to use namespaces, we need to have varients of these
useful macros that allow the export to be in a particular namespace.

I'd rather route this through linux-pm unless you have dependent changes.

Ok. 

The kxsd9 patch (4) is dependent on other changes queued for
the merge window in IIO. If we want to do it through linux-pm I'd
love it if we can manage to get the ground work in for the coming merge window.

So options are:

1) This patch alone via linux-pm and I queue the users up for next cycle
   Fine by me but always awkward to have infrastructure with no users.
2) First 3 patches via linux-pm so we have a user (scd30) in a low churn
   driver and I'll queue the rest for 5.19.  Fine by me as well.
   That goes on cleanly on 5.17-rc1 and there is nothing else in my review
   queue touching that driver.

I'm also interested to hear your view on the discussion going on in reply
to the cover letter. Specifically Paul suggested we 'only' have the
namespaced versions of these macros.

Thanks,

Jonathan

That would work for me.

Well, I'm a bit afraid that providing the namespaced versions only
would slow down the adoption.

Great.  Let's do that then.  Are you fine picking them from this thread, or
would you like me to resend with just those 3 patches as a fresh series?

Agreed, that's a concern and as Paul was happy with the route of
adding NS and perhaps looking eventually at dropping the non NS variant
I think we can move forward with this patch.

Hi Rafael,

I've not heard back from you, so have been assuming you'd pick those first
3 patches up from this series.  Is that a correct assumption?

Thanks,

This was my intention, but then I lost track of them and now I can't
find them in the linux-pm Patchwork.  Sorry about this.

Can you please resend just the 3 patches?
