will look into this, any idea for a more suitable location?

Maybe just a new file under lib/ for now?

Overly long line.  But we're also looking into generic helpers for
this kind of things, not sure if they made it to linux-next in the
meantime, but please check.

This is what I found in linux-next - note sure if you were referring to it

    iov_iter: Add ITER_XARRAY

No, that's not it.  Ira, what is the status of the memcpy_{to,from}_page
helpers?

Converting the entire kernel tree in one series has become unwieldy so I've
given up.

But I have a series to convert btrfs which I could release by the end of the
week.  That should be good enough to push the memcpy_*_page() support in.

I'm get it formatted and submitted,
Ira
