I've just created an ext2 partition (so no extents), and did some
quick benchmarks of those 2 commits. This is on the original system
(not my laptop), with the same config settings as before. All tests
initialised with -s 20 and tested with -j 80 -c 80.

30 seconds:

8800d8: 1327.983018 / 1317.848514
269e78: 1388.009819 / 1285.929100

5 minutes:

8800d8: 1744.446592 / 1729.602706
269e78: 1677.561277 / 1677.967873

10 minutes:

8800d8: 1753.147609 / 1806.600335
269e78: 1815.862842 / 1804.906769

So this appears to be okay.
