Subject: [PATCH] mm: Remove unused inline functions from include/linux/mm_inline.h
Date:   Thu, 22 Sep 2022 19:09:35 +0800

Precedence: bulk

Remove the following unused inline functions from mm_inline.h:
1. All uses of add_page_to_lru_list_tail() have
been removed since commit 7a3dbfe8a52b ("mm/swap: convert
lru_deactivate_file to a folio_batch"), and it can be replaced by
lruvec_add_folio_tail().

2. All uses of __clear_page_lru_flags() have
been removed since commit 188e8caee968 ("mm/swap: convert
__page_cache_release() to use a folio"), and it can be replaced
by __folio_clear_lru_flags().

They are useless, so remove them.
