   So, if fs creator is Linux then HURD doesn't try to use those
   fields?

As I recall it (don't have access to the source code here), the
file-system translator will return EOPNOTSUPP if you try and set a
passive translator on a non-Hurd owned file-system.  Passive
translators are the only kind of translators which write any kind of
data back to the acutal file-system.

For the case of st_author/i_author, when the file is created on a
non-Hurd owned file-system, it will simply return whatever
i_uid/st_uid is.

   Not that we will be in a rush to use these fields, but it would be
   good to know what i_mode_high is used for in case it ever becomes
   relevant for Linux we would want to keep it the same meaning as
   HURD.

Once again, as I recall it (a bit better this time), i_mode_high is
used for the actual bits that define if there is a translator (and
what kind) on a node or not.

Cheers.
