Maybe, but it's mighty useful in testing the file descriptor reclaiming code.

The iget(..., 0) thing has been fixed.

I'm not seeing that any more.

It's here -
	copy_stat:

		.ust_major   = MAJOR(src->st_dev),     /* device */
		.ust_minor   = MINOR(src->st_dev),

	do_stat_file:
		      .rdev		= MKDEV(buf.ust_major, buf.ust_minor),

Now that I have externfs_inode_info, either it or uml_stat looks redundant.
One more thing to clean up...
