It makes sense to me too that it might be better to get those submitted
to get more testing if there is no more comment about it.

I am guessing they should be targetting net-next tree to get more
testing as all the callers of page_frag API seem to be in the
networking, right?

Hi, David, Jakub & Paolo
It would be good if those patches are just cherry-picked from this
patchset as those patches with 'Reviewed-by' tag seem to be applying
cleanly. Or any better suggestion here?

Let's discuss that in patch 7.

Thanks for the time reviewing and reminding about the above.
It makes sense to have more time to have more reviewing as long as we
are making productive progress.
