Re: [PATCH 10/17] mm: rmap preparation for remap_anon_pages

Overall this looks a fairly small change to the rmap code, notably
less intrusive than the nonlinear vmas created by remap_file_pages.

Considering that remap_file_pages() was an unmitigated disaster, and
-mm has a patch to remove it entirely, I'm not at all convinced this
is a good argument.

We thought remap_file_pages() was a good idea, and it really really
really wasn't. Almost nobody used it, why would the anonymous page
case be any different?
