[00/13] More swap folio conversions

Message

These all seem like fairly straightforward conversions to me.
A lot of compound_head() calls get removed.  And page_swap_info(),
which is nice.  Passes my fairly limited testing.

Matthew Wilcox (Oracle) (13):
  mm: Return the folio from __read_swap_cache_async()
  mm: Pass a folio to __swap_writepage()
  mm: Pass a folio to swap_writepage_fs()
  mm: Pass a folio to swap_writepage_bdev_sync()
  mm: Pass a folio to swap_writepage_bdev_async()
  mm: Pass a folio to swap_readpage_fs()
  mm: Pass a folio to swap_readpage_bdev_sync()
  mm: Pass a folio to swap_readpage_bdev_async()
  mm: Convert swap_page_sector() to swap_folio_sector()
  mm: Convert swap_readpage() to swap_read_folio()
  mm: Remove page_swap_info()
  mm: Return a folio from read_swap_cache_async()
  mm: Convert swap_cluster_readahead and swap_vma_readahead to return a
    folio
