Subject: [PATCH v2 05/29] slab: rename gfpflags to allocflags
Date: Fri, 11 May 2012 14:44:07 -0300	[thread overview]
Message-ID: <1336758272-24284-6-git-send-email-glommer@parallels.com> (raw)
In-Reply-To: <1336758272-24284-1-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.
