Hi, Ted and Andreas

These two patches are the second version of the PATCH "ext4: fix unsafe
extent initialization". Instead of split extent in the first iteration,
it update the i_disksize if the zeroout region exceeds current
i_disksize, please review.

Thanks,
Yi.

-------
Changes since v1:
 - Add a patch to correct inode->i_size reading when converting
   initialized extent.
 - Instead of split extent, update i_disksize if necessary.

  ext4: use i_size_read() when converting initialized extent
