From 2f709f7bfd3d13f8878070a79e0983b5fac2225f Mon Sep 17 00:00:00 2001 From: Peter Xu Date: Tue, 5 Mar 2024 12:37:47 +0800 Subject: mm/treewide: replace pmd_large() with pmd_leaf() pmd_large() is always defined as pmd_leaf(). Merge their usages. Chose pmd_leaf() because pmd_leaf() is a global API, while pmd_large() is not.
