Fine by me, but generally that kind of search-and-replace is
better done differently:

1) patch replacing the definition of d_backing_inode() with
#define d_backing_inode d_inode

2) mail to Linus, asking to do mechanical search-and-replace
just prior to -rc1; see e.g. 7c0f6ba682b9 for example of
that being done.  In this case the script would be
sed -i -e "s/\<d_backing_inode\>/d_inode/g" $(git grep -l -w "d_backing_inode")
sed -i -e "/#define d_inode d_inode/d" include/linux/dentry.h
