  "message": "memory hotplug: make kmem_cache_node for SLUB on memory online avoid panic\n\nFix a panic due to access NULL pointer of kmem_cache_node at discard_slab()\nafter memory online.\n\nWhen memory online is called, kmem_cache_nodes are created for all SLUBs\nfor new node whose memory are available.\n\nslab_mem_going_online_callback() is called to make kmem_cache_node() in\ncallback of memory online event.  If it (or other callbacks) fails, then\nslab_mem_offline_callback() is called for rollback.\n\nIn memory offline, slab_mem_going_offline_callback() is called to shrink\nall slub cache, then slab_mem_offline_callback() is called later.\n\n[akpm@linux-foundation.org: coding-style fixes]\n[akpm@linux-foundation.org: locking fix]\n[akpm@linux-foundation.org: build fix]\nSigned-off-by: Yasunori Goto \u003cy-goto@jp.fujitsu.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
