Hello,

I would like to apply a new project "HTree Directory Index and Journal 
in ext2fs" in GSoC 2011. This project is not in ideas page. But this 
project can improve ext2fs in FreeBSD.

Last year, I have participated GSoC 2010 and have implemented a 
preallocation algorithm in ext2fs and make it can read ext4 file system 
in read-only mode. I have try to read htree dir index in ext4 read-only 
mode. Yet I don't finish it. I am plan to implement a htree dir index in 
ext2fs before midterm evaluation.

Next I will try to implement journal in ext2fs. I think I can borrow 
some ideas from WAPBL in NetBSD.

Best regards,
lz
