[net-next 0/3] optimisations and reorganisations of tcp_collapse

This patch series removes possible useless copying and collapsing while
not missing the chance when it is worth the effort. Also reorganizes it
and do some cleanups.

Koichiro Den (3):
  tcp: avoid useless copying and collapsing of just one skb
  tcp: do not tcp_collapse once SYN or FIN found
  tcp: keep tcp_collapse controllable even after processing starts
