Description

From Matt Ahrens's feature request at Delphix:

Want to have a kstat that tells us how much time we are spending in
dtrace_probe().  This will allow us to gauge the performance impact of any
dtrace analytics that we are running on customers' systems.

To make the dtrace kstats more easily accessible, they should be displayed by iostat -c.
