That doesn't produce any output.  Did you mean:

	xfs_io -c "statx -c" /dev/null

Further, this should work:

	warthog>xfs_io -c "statx -c" /dev/sda
	/dev/sda: Permission denied

but doesn't.

So I would have to make "-d dirfd" take an entry in the global var filetable
rather than an actual fd number?
