             Bug #: 14378
           Summary: dwarfless kprobe return probes don't support @entry()
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: translator
        AssignedTo: systemtap@sourceware.org
        ReportedBy: dsmith@redhat.com
    Classification: Unclassified


kernel.function().return probes support '@entry()', enabling them to get saved
entry-time expressions.

kprobe.function().return probes should also support '@entry()'.

(Better nd_syscall support needs this feature, since several syscall return
probes refer to entry variables.)
