Subject: Re: i_size error with the latest patchqueue

So I think what I need to do is to have scan_extent_node update two
variables; pb->last_block, and pb->last_block_used, where
pb->last_block_used doesn't get updated if the extent is not
initialized.

However, what we'll have to do is that if the two are different,
i_size must be at least pb->last_block_used*blocksize, but less than or
equal to pb->last_block*blocksize + (blocksize-1).
