It's interesting to compare these with the mostly-dynamic but
sometimes-static approach used in dtrace: almost any function
can be traced without great effort, but a few built-in
static trace points provide higher-level semantics.

A decent explanation of that was Brian Cantrill's comment
at http://lwn.net/Articles/244646/

I speculate that developers of particular kernel areas
would be active in creating and maintaining high-level and
correlated trace information, and end users could take
advantage of them, but being able to trace on, for example,
entry to an arbitrary function would be th next-most-used
functionality.
