From 5b80287a65da927742c6d43b1369bd5ed133aad1 Mon Sep 17 00:00:00 2001 From: Yaowei Bai Date: Thu, 14 Jan 2016 15:19:11 -0800 Subject: mm/mmzone.c: memmap_valid_within() can be boolean Make memmap_valid_within return bool due to this particular function only using either one or zero as its return value. No functional change.
