In the most recent revision, I've tried to assign the same rank and color
to certain classes of functions:
System Calls (accept, bind, close, connect, dup, ...)
Protocol Switch (pru_accept, pru_attach, pru_bind, pr_ctloutput, ...)
File Descriptor Switch (fo_read, fo_write, fo_poll, ...)
Socket File Descriptor Functions (soo_read, soo_write, ...)
In addition, I assigned the same color to certain classes of functions:
Almost System Calls (kern_bind, kern_connect, accept1, ...)
Protocol Upcalls to Socket Layer (soisdisconnected, soisdisconnected, ...)
I'm going to experiment with grouping later today.
