       struct dentry * d_backing_dentry(struct dentry * upper);

       This is the helper that should be used to get the dentry of the inode that will be used if
       this dentry were opened as a file. It may be the upper dentry or it may be a lower dentry
       pinned by the upper.

       Normal filesystems should not use this to access their own dentries.
