File System query

I have the following question regarding the linux file system

In linux/fs.h I saw the "struct super_operation" structure. I saw that two
of the member function pointers are write_inode() and put_inode(). But In
the ext2,ext3,ext4 implementation i saw that it uses the only write_inode()
function. So, what is the reason behind keeping the other pointers ?
