Hi, i've finaly found time to review and test ext4 patches.
And i have some fixes:
[1] One more one line fix for ext4-block-reservation patch. IMHO
it is better to merge it with my previous block reservation fixes.
[2] Fix compilation with EXT_DEBUG
[3] Some code cleanup

Fix compilation with EXT_DEBUG, also fix leXX_to_cpu convertions.

- Replace math equation to it's macro equivalent
- make ext4_ext_grow_indepth() indexes/leaf correct
