This would break the circular lock dependency,\nwhere, for example, the current thread already locks j1939_socks_lock\nand attempts to acquire sk_session_queue_lock, and at the same time,\nanother thread attempts to acquire j1939_socks_lock while holding\nsk_session_queue_lock.\n\nNOTE: This patch along does not fix the unregister_netdevice bug\nreported by Syzbot; instead, it solves a deadlock situation to prepare\nfor one or more further patches to actually fix the Syzbot bug, which\nappears to be a reference counting problem within the j1939 codebase.\n\n[mkl: remove unrelated newline change]"
