The hotplug code does not handle node_states[N_NORMAL_MEMORY] correctly, it may corrupt the memory. And we ensure the SLUB do NOT respond when node_states[N_NORMAL_MEMORY] is not changed. The patchset is based on mainline(3d0ceac129f3ea0b125289055a3aa7519d38df77) CC: David Rientjes Cc: Minchan Kim CC: KOSAKI Motohiro CC: Yasuaki Ishimatsu CC: Rob Landley CC: Andrew Morton CC: Jiang Liu CC: Kay Sievers CC: Greg Kroah-Hartman CC: Mel Gorman CC: 'FNST-Wen Congyang' CC: linux-doc@vger.kernel.org CC: linux-kernel@vger.kernel.org CC: linux-mm@kvack.org Lai Jiangshan (2): memory_hotplug: fix possible incorrect node_states[N_NORMAL_MEMORY] slub, hotplug: ignore unrelated node's hot-adding and hot-removing Documentation/memory-hotplug.txt | 5 +- include/linux/memory.h | 1 + mm/memory_hotplug.c | 136 +++++++++++++++++++++++++++++++++----- mm/slub.c | 4 +- 4 files changed, 127 insertions(+), 19 deletions(-) -- 1.7.4.4 -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
