From bb00a789e565b96c52b2224c2280f7ac83175bec Mon Sep 17 00:00:00 2001 From: Yaowei Bai Date: Thu, 19 May 2016 17:11:29 -0700 Subject: [PATCH] mm/vmalloc.c: is_vmalloc_addr() can return bool Make is_vmalloc_addr() return bool to improve readability due to this particular function only using either one or zero as its return value.
