When probing the usbnet device, executing usbnet_link_change(dev, 0, 0);\nput the kevent work in global workqueue. However, the kevent has not yet\nbeen scheduled when the usbnet device is unregistered. Therefore, executing\nfree_netdev() results in the \"free active object (kevent)\" error reported\nhere.\n\n2. Another factor is that when calling usbnet_disconnect()->unregister_netdev(),\nif the usbnet device is up, ndo_stop() is executed to cancel the kevent.\nHowever, because the device is not up, ndo_stop() is not executed.\n\nThe solution to this problem is to cancel the kevent before executing\nfree_netdev()."}],"metrics":{},"references":[{"url":"https://git.kernel.org/stable/c/285d4b953f2ca03c358f986718dd89ee9bde632e","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/2ce1de32e05445d77fc056f6ff8339cfb78a5f84","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/3a10619fdefd3051aeb14860e4d4335529b4e94d","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/420c84c330d1688b8c764479e5738bbdbf0a33de","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/43005002b60ef3424719ecda16d124714b45da3b","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/5158fb8da162e3982940f30cd01ed77bdf42c6fc","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/88a38b135d69f5db9024ff6527232f1b51be8915","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/9a579d6a39513069d298eee70770bbac8a148565","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"}]}}]}
