This conflicts with the current mmotm tree because of Johannes' {un}charge rewrite.
Anyway the comment is not up-to-date anyway. __delete_from_page_cache is
called from more places and I do not see quite a good reason why to keep
this in the documentation.
I would just remove this note as it doesn't serve any useful purpose.
Thanks for your reply.
Just take a quick look at Johannes' patch of rewriting uncharge API. I'll
resend a patch with the note removed.
Thanks,
Lei
