Technically yes.
But then I grepped include/ and it is widely used, even by core kernel
headers. Why is that ? Maybe just to keep prototype consistent ?
Also init.h says:
* If the function has a prototype somewhere, you can also add
* __init between closing brace of the prototype and semicolon:
*
* extern int initialize_foobar_device(int, int, int) __init;
Hmm, I understand that it is just saying that __init can be used after
function's name instead of just before, but isn't it also suggesting
that headers may also have it (maybe just to keep it consistent) ?
