Umm, I don't think so. ext3 i_blocks is

Hi all,
In testing large (>4TB) device support on 2.6, I've been using a simple
write/verify test to check both block device and regular file
correctness.
Set to write 1MB poison patterns for the whole of a file until EOF is
encountered, it worked just fine on ext3: the file got a short write
