Hi Brendan,

Nice - and I'd been thinking along the same lines, that it wouldn't be
hard to write a helper, and published something to do it all from
ftrace: http://www.brendangregg.com/blog/2015-06-28/linux-ftrace-uprobe.html

Ah, missed that one, much cleaner than my attempt, thanks.

The only thing I would miss is the "match symbol by regular expression"
feature from my script. Needing to work with C++, where each Foo has new and
exciting ideas on how to implement Foo::bar(), tracing the bar's Pokemon
style (probe em all!) often helps me maintain sanity :-)

Cheers,
 Benjamin
