Look at: http://www.freebsd.org/cgi/cvsweb.cgi/src/usr.bin/ktrace/ktrace.c http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/kern/kern_ktrace.c And from the checkins list on each of these, determine who is maintaining the code. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
