From 4b34c3e7026524f1831c880ce9cad718d47080ba Mon Sep 17 00:00:00 2001 From: "Matthew Wilcox (Oracle)" Date: Tue, 5 Aug 2025 18:23:00 +0100 Subject: [PATCH] mm: reimplement folio_is_fsdax() For callers of folio_is_fsdax(), we save a folio->page->folio conversion. Callers of is_fsdax_page() simply move the conversion of page->folio from the implementation of page_pgmap() to is_fsdax_page().
