My gut reaction is: "not another bunch of xattr syscalls!".  It
doesn't feel right, this interface is too specialized to warrant a
full set of filesystem syscalls.

Al Viro is right that there are problems with symlinks.  What we
really want here is a sort of symlink that doesn't get followed.  One
way to provide that is to create a kernel internal "handle" filesystem
and direct open_by_handle() to that for anything not a directory or a
regular file.

Thanks,
Miklos
