From: Vishal Moola (Oracle) Date: Tue, 1 Nov 2022 17:53:26 +0000 (-0700) Subject: folio-compat: remove lru_cache_add() X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=6e1ca48d0669b0f5efcbaa051b23cd8e651a1614;p=linux.git folio-compat: remove lru_cache_add() 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.
