it 1138 times (:-() in casts and a few more times in declarations. This change is null for the i386. The type has to be `typedef int vop_t(void *)' and not `typedef int vop_t()' because `gcc -Wstrict-prototypes' warns about the latter. Since vnode op functions are called with args of different (struct pointer) types, neither of these function types is any use for type checking of the arg, so it would be preferable not to use the complete function type, especially since using the complete type requires adding 1138 casts to avoid compiler warnings and another 40+ casts to reverse the function pointer conversions before calling the functions.
