Eric Dumazet says:

====================
tcp: small code reorg

Replace a WARN_ON_ONCE() that never triggered
to DEBUG_NET_WARN_ON_ONCE() in reqsk_free().

Move inet_reqsk_alloc() and reqsk_alloc()
to inet_connection_sock.c, to unclutter
net/ipv4/tcp_input.c and include/net/request_sock.h
====================
