This patch add project inode identifier. Project ID may be used as
auxiliary owner specifier in addition to standard uid/gid.

Hi,
First of all please excuse me for a very very late replay.
Where were some very urgent work to do, Please excuse me one more time.

  I would just join patches 1 and 2. One without the other looks a bit
dumb... Otherwise I'm OK with the changes. I can take these two patches
through my tree when filesystem maintainers agree they want this feature and
are going to merge corresponding fs patches...

Ok, seem reasonable will redo.
