     mm-rmap-use-folio_page_swap_entry-in-ttu_anon_swapbacked_folio.patch

This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

We already have the folio here, so use folio_page_swap_entry() instead of
going through page_swap_entry().  This saves a call to compound_head().

No functional change.
