In commit 198bc90e0e73("tcp: make sure init the accept_queue's spinlocks
once"), the spinlocks of accept_queue are initialized only when socket is
created in the inet4 scenario. The locks are not initialized when socket
is created in the inet6 scenario. The kernel reports the following error:
INFO: trying to register non-static key.
The code is fine but needs lockdep annotation, or maybe
you didn't initialize this object before use?
turning off the locking correctness validator.
