Change 97463 by jb at jb_freebsd2 on 2006/05/19 20:29:01

	It's time for the Function Boundary Tracing (FBT) provider. This one
	provides probes associated with the entry to and return from most functions
	kernel and kernel modules. The Solaris docs say: "even on the smallest
	Solaris systems, FBT will provide on the order of 20,000 probes."
	
	The advice from Sun was to port this provider before SDT, but I decided
	SDT was easier. 8-)
