[DTrace-devel] [RFC 0/2] dtrace: print() action support

[Alan Maguire]

The print() action supports CTF-powered dumping of data pointed
to by the argument passed in [1].  This is a useful feature for
kernel debugging, so it would be great to have in DTrace v2.

Alan Maguire (2):
  dtrace: support print() action for DTrace v2
  unittest/print: add unit tests to verify print() action behaviour
