Yes, I would love to get rid of them. There are just too many users.
1332 users of d_inode
176 users of d_backing_inode

Similarly, file_inode() with 1020 users is another candidate.

Introduced in -
496ad9aa8ef4 ("new helper: file_inode(file)")
but made unnecessary in -
dd37978c50bc ("cache the value of file_inode() in struct file")

I will work on a patch to clean all.
