[CentOS] The state of xfs on CentOS 6?

We're looking at getting an HBR (that's a technical term, honkin' big
RAID). What I'm considering is, rather than chopping it up into 14TB or
16TB filesystems, of using xfs for really big filesystems. The question
that's come up is: what's the state of xfs on CentOS6? I've seen a number
of older threads seeing problems with it - has that mostly been resolved?
How does it work if we have some *huge* files, and lots and lots of
smaller files?
