Replace READ_ONCE() with the existing standard page table accessor for PUD aka pudp_get() in pud_trans_unstable(). This does not create any functional change for platforms that do not override pudp_get(), which still defaults to READ_ONCE(). Cc: Andrew Morton Cc: David Hildenbrand Cc: Lorenzo Stoakes Cc: Mike Rapoport Cc: linux-mm@kvack.org Cc: linux-kernel@vger.kernel.org Signed-off-by: Anshuman Khandual --- This patch applies both on v7.0-rc1 and mm-unstable. Part of the D128 series but independent. Hence could be considered on its own. https://lore.kernel.org/all/20260224051153.3150613-4-anshuman.khandual@arm.com/ include/linux/pgtable.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/include/linux/pgtable.h b/include/linux/pgtable.h index a50df42a893f..d4826447bc93 100644 --- a/include/linux/pgtable.h +++ b/include/linux/pgtable.h @@ -1989,7 +1989,7 @@ static inline int pud_trans_unstable(pud_t *pud) { #if defined(CONFIG_TRANSPARENT_HUGEPAGE) && \ defined(CONFIG_HAVE_ARCH_TRANSPARENT_HUGEPAGE_PUD) - pud_t pudval = READ_ONCE(*pud); + pud_t pudval = pudp_get(pud); if (pud_none(pudval) || pud_trans_huge(pudval)) return 1; -- 2.30.2
