The commit that introduced the problem is

ae9efd05a9860b53691884f5fed40d37fc3d7edb e2fsck: 3 level hash tree
directory optimization

specifically this line

dx_db->previous = i ? ext2fs_le32_to_cpu(ent[i-1].block & 0x0ffffff) : 0;


I think it's supposed to be like this instead.

dx_db->previous = i ? ext2fs_le32_to_cpu(ent[i-1].block) & 0x0ffffff : 0;


Thanks!
