From b4ad0c7e004a2cc0e52790eff72f5176b59ca386 Mon Sep 17 00:00:00 2001 From: Yaowei Bai Date: Thu, 14 Jan 2016 15:18:54 -0800 Subject: [PATCH] mm/memblock.c: memblock_is_memory()/reserved() can be boolean Make memblock_is_memory() and memblock_is_reserved return bool to improve readability due to these particular functions only using either one or zero as their return value. No functional change.
