Subject: [PATCH 1/4] slab: rename gfpflags to allocflags
Date: Thu, 14 Jun 2012 16:17:21 +0400	[thread overview]
Message-ID: <1339676244-27967-2-git-send-email-glommer@parallels.com> (raw)
In-Reply-To: <1339676244-27967-1-git-send-email-glommer@parallels.com>

A consistent name with slub saves us an acessor function.
In both caches, this field represents the same thing. We would
like to use it from the mem_cgroup code.
