Hi, I was having a tour in the kernel sources and I found some codes
that I can't understand why. Like this in ppp:

int
ppp_init (struct device *dev)
{
static int first_time = 1; <== define to 1
int answer = 0;

if (first_time) { <== check if is 1, why ? any special special reason?
first_time = 0;
answer = ppp_first_time();
if (answer == 0)
(void) register_symtab (&ppp_syms);
}
if (answer == 0)
answer = -ENODEV;
return answer;
}

I found many more codes like this in the source, I cant remeber where anymore.
