[merged mm-stable] folio-compat-remove-lru_cache_add.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: folio-compat: remove lru_cache_add()
has been removed from the -mm tree.  Its filename was
     folio-compat-remove-lru_cache_add.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

Subject: folio-compat: remove lru_cache_add()
Date: Tue, 1 Nov 2022 10:53:26 -0700

There are no longer any callers of lru_cache_add(), so remove it.  This
saves 79 bytes of kernel text.  Also cleanup some comments such that
they reference the new folio_add_lru() instead.
