From 949bed2f5764435715e3d6dd3ab6dd4dbd890a71 Mon Sep 17 00:00:00 2001 From: Chen Gang Date: Tue, 2 Aug 2016 14:03:42 -0700 Subject: include: mman: use bool instead of int for the return value of arch_validate_prot For pure bool function's return value, bool is a little better more or less than int.
