I'm not sure I understand your statement here, but...
My point is, I'd rather have things like printk() and
strscpy() be marked with (an imaginary) __need_not_check,
than the way things are, with only certain functions being
marked __must_check.
In my view, if a function returns a value, all callers
of that function ought to be checking it. If the return
value is not necessary it should be a void function if
possible.
I don't expect the world to change, but I just think the
default should be "must check" rather than "check optional".
