It should not be too hard. Actually, after I mirgrated CIRCLEQ to TAILQ in nvi2's code, https://github.com/lichray/nvi2/commits/master?page=9 FreeBSD base already has absolutely no code using CIRCLEQ. So my suggestion is simple: nuke it out. -- Zhihao Yuan, ID lichray The best way to predict the future is to invent it. ___________________________________________________ 4BSD -- http://4bsd.biz/
