This makes every inetpeer struct consume 8 more bytes, and on some
systems we have can have many of these objects active.  That space
savings is why this was done the way it was.

It would be nice to have "tailq" like interfaces in linux/list.h
for situations like this.

Please do not submit a patch implementing that until the 2.6.25
merge window, however, thanks.
