xfs_growfs doesn't detect new blocks

[Fredrik Tolf <fredrik@xxxxxxxxxxxxx>]

Hi!

I recently extended a logical volume that I have XFS on, and for some
reason, xfs_growfs wouldn't detect the new blocks until I had umounted
the filesystem and then remounted it (which, naturally, isn't really
desirable).

I'm using the Sistina LVM2 and XFS that come with the stock
2.6.0-test10 kernel. Is this a known issue, or did I do something
wrong, mayhap?
