Log:
  Document varadic args as int, since you can't have short varadic args (they are
  promoted to ints).
  
  - `mode_t` is `uint16_t` (`sys/sys/_types.h`)
  - `openat` takes variadic args
  - variadic args cannot be 16-bit, and indeed the code uses int
  - the manpage currently kinda implies the argument is 16-bit by saying `mode_t`
