Since commit c14b78e7 ("netfilter: nfnetlink: add mutex per subsystem") building nefnetlink.o without CONFIG_PROVE_RCU set, triggers this GCC warning: net/netfilter/nfnetlink.c:65:22: warning: ‘nfnl_get_lock’ defined but not used [-Wunused-function] The cause of that warning is, in short, that rcu_lockdep_assert() compiles away if CONFIG_PROVE_RCU is not set. Silence this warning by open coding nfnl_get_lock() in the sole place it was called, which allows to remove that function.
