But struct richace_xattr has a hole now.  

There's ample of space left in the 16-bit field; I don't think there is
a need to extend it.  If the need should ever arise, we can still define
a new version of the xattr format.  Also, this change creates a hole in
struct richace_xattr; we can't do that.

Can the ACE4_UNIXID_WHO flag please be removed again?  It isn't needed,
it just creates a mess.

Thanks,
Andreas
