Re: DTrace FBT provider heads-up

I've committed the Function Boundary Trace provider to NetBSD current.
This DTrace provider automatically instruments every function in the
kernel with an entry and exit probe. The probes have true zero-probe
effect (i.e. they don't affect the system when disabled), as they don't
actually exist in the code until they're enabled. When enabled a probe
directly patches the function to add a jump into FBT provider at the
function's entry or exit points.
Really nice :) Thanks for your work.
