             Bug #: 13450
           Summary: get rid of most/all probe-alias "?" (optional) markup
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: tapsets
        AssignedTo: systemtap@sourceware.org
        ReportedBy: fche@redhat.com
    Classification: Unclassified


Probe aliases defined thusly:

    probe foo = bar?
      { }

does not do a lot for a script user.  It quietly fails when the
underlying bar probe point is not present.  If the end-user script
wishes to allow this, it should be written with the optional markup
of its own:

    probe foo ?  
      { }

We should review the tapset and generally get rid of as many of 
these optional markers (conditional on %( version %) ) as possible.
