From 6e8cda4c2c87b2a44828e651a10705647a6fd542 Mon Sep 17 00:00:00 2001 From: Matthew Wilcox (Oracle) Date: Fri, 12 Apr 2024 20:35:03 +0100 Subject: mm: convert hugetlb_page_mapping_lock_write to folio The page is only used to get the mapping, so the folio will do just as well. Both callers already have a folio available, so this saves a call to compound_head().
