Well, this isn't quite correct. The mballoc code only tries to allocate "large" files on power-of-two boundaries, where large is 64kB by default, but is tunable in /proc. For smaller files it tries to pack them together into the same block, or into gaps that are exactly the size of the file.
How does ext4 act on growing files? I.e., creating a tarball that, obviously, starts at 0 bytes and then grows to multi-GB?
