[DTrace-devel] [PATCH v3 0/4] add support for stapsdt probes

[Alan Maguire]

As well as using dtrace -G to generate USDT probes, programs and
libraries may have added static probes via stapsdt ELF notes.
This series adds support for such probes.  Patch 1 adds the support,    
while patches 2-4 add tests covering that support.

Changes since v2:

- updated terminology to distinguish stapsdt from USDT probes

Alan Maguire (4):
  support stapsdt ELF-note-defined static probes
  selftests/usdt: add test for stapsdt note-defined probe firing, args
  selftests/usdt: add test for stapsdt notes in shared library
  selftests/usdt: add test covering different forms of stapsdt note args
