Hello,

  here is the second iteration of my patches to remove ext3 filesystem driver.
Changes since the first version are:
* Regenerated the patch removing ext3 (using git format-patch -D) so that it's
  not so huge
* Added Kconfig option handling so that old configs with EXT3_FS set but not
  EXT4_FS set still result in a kernel supporting ext3 filesystem
* Created a patch updating ext4 Kconfig entry to assure users their old ext3
  filesystems stay on-disk format compatible
* Added acks

If there won't be further objections, I will queue the series in my tree for
the next merge window.
