Message

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.

Matthew Wilcox (Oracle) (8):
  filemap: Remove readahead_page()
  mm: Remove offset_in_thp()
  iov_iter: Convert iter_xarray_populate_pages() to use folios
  iov_iter: Convert iov_iter_extract_xarray_pages() to use folios
  filemap: Remove find_subpage()
  filemap: Convert __readahead_batch() to use a folio
  filemap: Remove readahead_page_batch()
  mm: Delete thp_nr_pages()
