From: Konstantin Khlebnikov Date: Fri, 2 Oct 2015 10:18:22 +0000 (+0300) Subject: ovs: do not allocate memory from offline numa node X-Git-Tag: v4.3-rc7~23^2~41 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=598c12d0ba6de9060f04999746eb1e015774044b;p=profile%2Fcommon%2Fplatform%2Fkernel%2Flinux-artik7.git ovs: do not allocate memory from offline numa node When openvswitch tries allocate memory from offline numa node 0: stats = kmem_cache_alloc_node(flow_stats_cache, GFP_KERNEL | __GFP_ZERO, 0) It catches VM_BUG_ON(nid < 0 || nid >= MAX_NUMNODES || !node_online(nid)) [ replaced with VM_WARN_ON(!node_online(nid)) recently ] in linux/gfp.h This patch disables numa affinity in this case.
