Re: remap_file_pages() use

[Jeff Smith]

I've got no real issues at this point, but could you perhaps elaborate
a bit on the rough order of magnitude of "long" time and what cases
would be slower? I'm pretty sure that some places I've worked that
still have some remap_file_pages() logic in place aren't too religious
about checking dmesg.
