It would be a global no matter which form we use, but for
maintainability reasons I generally prefer a static put right before
the function that uses it:
static cpumask_t mask;
static func(...)
{
}
That makes it really apparent that it's a global - statics are easily
missed when hiding amongst local variables.
Thanks,
Ingo
