[extfs] Final Report

[gnehzuil]

Status:

Last week I tried to implement ext2_readdir() function with hash 
directory index. The implementation in Linux requires directory name. 
However in FreeBSD it is hard to get it. So I dont have a good solution 
to implement it. If possible, I will implement it after soc.


Final Status:

Although I don't implement ext2_readdir() function with hash directory 
index, the project is done because ext2fs can read ext4 read-only mode 
with DIR_INDEX feature.
