Anyways, yes I've added the $DEBUGFS command so we can observe the
extent structure, but the filefrag would look something like this (last
few extents):

...
337: 674.. 674: 10130.. 10130: 1:
338: 676.. 676: 10132.. 10132: 1:
339: 678.. 678: 10134.. 10134: 1:
340: 679.. 680: 10135.. 10136: 2: last,eof

Notice that the last 2 extents are logically and physically continuous
but not merged.

I see, thanks for the example!
