The only reason I mentioned it was the old function name
was aligned that way with arguments aligned to the open
parenthesis.

Renaming the function should keep the same alignment style
and not just rename the function.

-	int (*fault)(const struct vm_special_mapping *sm,
+	vm_fault_t (*fault)(const struct vm_special_mapping *sm,
 		     struct vm_area_struct *vma,
 		     struct vm_fault *vmf);

Here the previous indent was 2 tabs, 5 spaces
