This certainly needs some motivation in the commit message, because it is not
at all clear why this is needed.  Sure, the next patch in the series uses it
outside of dtrace_probe, but that patch also does not provide any motivation
on why that is needed (and same with the patch after that).  So, these three
patches (16-18) should be combined, and bear a commit message that explains
why this is needed.  That will help in reviewing this code.
