I am doing a project,in which i am embedding inodes in directory entry.
1. i have changed the ext3_dir_entry_2 structure and included in it a member of struct ext3_inode.
2.also changed EXT3_DIR_REC_LEN (added 132 bytes as it is size of inodes).
3.Have made similar changes in mke2fs source code and formated my dev wth this code and then mounted the filesystem in which i have made changes.
Could you tel me where more am i supposed to make changes....bcoz the kernel crashes and at times there is segmentation fault when checking for compatibility with ext2 and ext3 structures.

i got this idea from: http://lwn.net/Articles/190224/
If anyone could help me for how to go about this project.
thanks....
