The default in XFS is now to restrict inode numbers to 32 bits;
however there is an "ino64" option that allows them to reach
64 bits internally, possibly breaking other applications.

(I see that the linux inode number is an unsigned long, so this
is probably the limiting factor on a 32 bit box).

The Inode numbers in xfs are sparse, though, so I'm not sure how to
calculate the actual number of files you can fit on a filesystem.

Steve can probably answer this succinctly.
