From 524984ff66ee4b63264dffe568c3547a20b4136c Mon Sep 17 00:00:00 2001 From: "Matthew Wilcox (Oracle)" Date: Wed, 19 Oct 2022 19:33:31 +0100 Subject: mm: convert find_get_incore_page() to filemap_get_incore_folio() Return the containing folio instead of the precise page. One of the callers wants the folio and the other can do the folio->page conversion itself. Nets 442 bytes of text size reduction, 478 bytes removed and 36 bytes added.
