From: Konstantin Khlebnikov <khlebnikov@yandex-team.ru> Date: Fri, 02 Oct 2015 13:18:22 +0300 > 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. > > Signed-off-by: Konstantin Khlebnikov <khlebnikov@yandex-team.ru> Applied, but this should probably use NUMA_NO_NODE unconditionally. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
