Subject: [PATCH] mm/slub.c: keep red_left_pad being zero without SLAB_RED_ZONE flag
Date: Fri, 4 Jan 2019 18:09:41 +0800 [thread overview]
Message-ID: <20190104100941.29872-1-rocking@whu.edu.cn> (raw)
It seems more clear for red_left_pad to be zero despite not being used
without SLAB_RED_ZONE flag.
