Eric Dumazet 84c156a351 tcp: add receive queue awareness in tcp_rcv_space_adjust()
[ Upstream commit ea33537d82 ]

If the application can not drain fast enough a TCP socket queue,
tcp_rcv_space_adjust() can overestimate tp->rcvq_space.space.

Then sk->sk_rcvbuf can grow and hit tcp_rmem[2] for no good reason.

Fix this by taking into acount the number of available bytes.

Keeping sk->sk_rcvbuf at the right size allows better cache efficiency.
