This is more DragonFly BSD related than it is related to me, but there is no DragonFly post in the "Journals" section (yet).

I finally got that little push needed to clean up my patch for KTR yesterday. You can have a look at it yourself here: http://eirikn.kerneled.org/dragonfly/ktr.patch
This is a port of the version in FreeBSD -CURRENT with some moderations, I have among other things removed the CTRx() and replaced all those macros with just CTR() which handles an unknown number of arguments in printf style.
