From 562beb7235abfebdd8366e0664a5c3d1e597b990 Mon Sep 17 00:00:00 2001 From: Miaohe Lin Date: Thu, 24 Mar 2022 18:13:27 -0700 Subject: mm/huge_memory: make is_transparent_hugepage() static It's only used inside the huge_memory.c now. Don't export it and make it static. We can thus reduce the size of huge_memory.o a bit.
