Why would you want to reuse a page about which you have no idea about

I mean this needs a deep justification!
reusing could not reuse page with page_mapcount > 0; it only reuse
a pure file page without mmap. only file pages producted by rw
syscall can be reuse; so no AF consideration for it and just use
active/inactive flag to distinguish.
I am sorry but I do not follow.
