From: Cong Wang <redacted> tcf_action_init_1() loads tc action modules automatically with request_module() after parsing the tc action names, and it drops RTNL lock and re-holds it before and after request_module(). This causes a lot of troubles, as discovered by syzbot, because we can be in the middle of batch initializations when we create an array of tc actions. [...]
