sys/kern : uipc_socket.c
sys/netinet : tcp_input.c tcp_output.c tcp_usrreq.c
Log message:
Use per-sockbuf mutex(9) to protect `so_snd' buffer of tcp(4) sockets.
Even for tcp(4) case, sosend() only checks `so_snd' free space and
sleeps if necessary, actual buffer handling happens in solock()ed PCB
layer.
Only unlock sosend() path, the somove() is still locked exclusively. The
"if (dosolock)" dances are useless, but intentionally left as is.
Tested and ok by bluhm.
