He was probably referring to problems with inode numbers > 64 bits,
which could be alleviated by making the inode size greater, IIRC.
The Linux XFS code has been restricting inode numbers by other means
for quite some time now, so as long as you don't have ancient code
you're probably fine.

Dredge up that post again, if it was from this year please post
the URL and I'll take a look, maybe Steve was talking about another
issue that I'm not remembering at the moment...
