From: Dan Carpenter <dan.carpenter@xxxxxxxxxx> This patch looks like it should be in the 3.9-stable tree, should we apply it? ------------------ From: "Dan Carpenter <dan.carpenter@xxxxxxxxxx>" commit cc0f868d8adef7bdc12cda132654870086d766bc upstream ->remote_rx_info and ->rx_info are struct ntb_rx_info pointers. If we add sizeof(struct ntb_rx_info) then it goes too far.
