Subject: filemap: remove readahead_page()
Date: Wed, 2 Apr 2025 22:06:03 +0100

Patch series "Misc folio patches for 6.16".

Remove a few APIs that we've converted everybody from using.  I also found
a few places that extract a page pointer from i_pages, which will be an
invalid thing to do when we separate pages from folios.


This patch (of 8):

All filesystems have now been converted to call readahead_folio() so we
can delete this wrapper.
