Subject: [PATCH 1/6] memcg: replace unsigned long by u64 to avoid overflow
Date: Sat, 23 Jun 2012 14:15:34 +0800	[thread overview]
Message-ID: <1340432134-5178-1-git-send-email-liwp.linux@gmail.com> (raw)

From: Wanpeng Li <liwp-23VcF4HTsmIX0ybBhKVfKdBPR1lH4CV8@public.gmane.org>

Since the return value variable in mem_cgroup_zone_nr_lru_pages and
mem_cgroup_node_nr_lru_pages functions are u64, so replace the return
value of funtions by u64 to avoid overflow.
