inet_diag: Generalize inet_diag dump and get_exact calls
Introduce two callbacks in inet_diag_handler -- one for dumping all sockets (with filters) and the other one for dumping a single sk. Replace direct calls to icsk handlers with indirect calls to callbacks provided by handlers. Make existing TCP and DCCP handlers use provided helpers for icsk-s. The UDP diag module will provide its own. Signed-off-by: Pavel Emelyanov <xemul@parallels.com> Signed-off-by: David S. Miller <davem@davemloft.net>
