  "message": "cfq-iosched: Don\u0027t update group weights when on service tree\n\nVersion 3 is updated to apply to for-2.6.39/core.\n\nFor version 2, I took Vivek\u0027s advice and made sure we update the group\nweight from cfq_group_service_tree_add().\n\nIf a weight was updated while a group is on the service tree, the\ncalculation for the total weight of the service tree can be adjusted\nimproperly, which either leads to bad service tree weights, or\npotentially crashes (if total_weight becomes 0).\n\nThis patch defers updates to the weight until a group is off the service\ntree.\n\nSigned-off-by: Justin TerAvest \u003cteravest@google.com\u003e\nAcked-by: Vivek Goyal \u003cvgoyal@redhat.com\u003e\nSigned-off-by: Jens Axboe \u003cjaxboe@fusionio.com\u003e\n",
