Yes, sorry, I meant "small files".

No, 2.6.25.4 does not have barriers enabled. It's in the latest
post-2.6.25.5 git repository (which also has the fix so that
barriers=1 doesn't cause an OOPS if you are doing the test on a LVM
device which doesn't support barriers). Sorry, I wasnt sure if you
were using any of the ext4 patches, and I didn't know whether you were
testing on a raw device or an LVM device.
