            Bug ID: 28244
           Summary: linux objtool imposes symbol length limits on
                    generated function names
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: translator
          Assignee: systemtap at sourceware dot org
          Reporter: fche at redhat dot com
  Target Milestone: ---

Some function/symbol names generated for probes/functions encode stap
tapset/source file name paths.  These can get long, but that's not usually a
problem.  However, linux objtool (in recent kernels) is invoked during the
kbuild process, and it imposes a 128-char limit.  It looks like we have no
choice but to shorten these symbol names.
