Here's an example, spelled out:

Grow file 1.
Chunk A fills up.
Allocate continuation inode for file 1 in chunk B.
Chunk A gets some free space.
Chunk B fills up.
Pick chunk A for allocating next block of file 1.
Try to look up a continuation inode for file 1 in chunk A.
Continuation inode for file 1 found in chunk A!
Attach newly allocated block to existing inode for file 1 in chunk A.

So far, so good (and the slides are helpful, tx!). What happens when
file 1 keeps growing and chunk A fills up (and chunk B is still full)?
Can the same continuation inode also point at chunk C, where the file
is going to grow to?
