Subject: [Patch V3 4/9] openvswitch: Replace cpu_to_node() with cpu_to_mem() to support memoryless node
Date: Mon, 17 Aug 2015 11:19:01 +0800 [thread overview]
Message-ID: <1439781546-7217-5-git-send-email-jiang.liu@linux.intel.com> (raw)
In-Reply-To: <1439781546-7217-1-git-send-email-jiang.liu@linux.intel.com>
Function ovs_flow_stats_update() allocates memory with __GFP_THISNODE
flag set, which may cause permanent memory allocation failure on
memoryless node. So replace cpu_to_node() with cpu_to_mem() to better
support memoryless node. For node with memory, cpu_to_mem() is the same
as cpu_to_node().
This change only affects performance and shouldn't affect functionality.
