            Bug ID: 18714
           Summary: bring back   process.statement.absolute probes
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: runtime
          Assignee: systemtap at sourceware dot org
          Reporter: fche at redhat dot com
  Target Milestone: ---

While inode-uprobes makes $subject probe type not trivially available, we
should still be able to hack around it in the runtime.  Given the requested
virtual address, aat registration time we could walk the process address space,
find the inode & offset corresponding to that address (if any!), and place a
inode+offset uprobe there.  (This doesn't help non-inode gaps in the address
space, alas.)
