Dazuko could use the exported d_path. Then the filename the driver reports
will be relative to the current root of the process that made the file
access. But this is not a problem. The process which gets the dazuko events
can easily check readlink /proc/PID/root and prepend that to the filename in
the event.
What do you think, John? Could you make dazuko use d_path on Linux?
