From c05995b7ec2a73bf813a8944978e175f8e4ec3ac Mon Sep 17 00:00:00 2001 From: Peter Xu Date: Tue, 5 Mar 2024 12:37:50 +0800 Subject: mm/treewide: align up pXd_leaf() retval across archs Even if pXd_leaf() API is defined globally, it's not clear on the retval, and there are three types used (bool, int, unsigned log). Always return a boolean for pXd_leaf() APIs.
