ERROR: do not initialise statics to false

Question about git commit rule

I git commit a patch,

The patch has a "static int xxxxxxxxxxxxxxxxxxxxxxxxxx = 0;"

It show error messge "ERROR: do not initialise statics to false"

Why can't initialize a static variable = false in function ?

All static variable that is uninitialize are moved to BSS section.

Linux initialize these static variable to zero in BSS section.

So just write "static variable" in function.

Example :

incorrect.c

#include <stdio.h>

int main()

{

        static int xxxxxxxxxxxxxxxxxxxxxxxxxx = 0;

        static int aaaaaaaaaaaaaaaaaaaaaaaaaa = 0;

        printf("exit \n");

}

correct.c

#include <stdio.h>

int main()

{

        static int xxxxxxxxxxxxxxxxxxxxxxxxxx;

        static int aaaaaaaaaaaaaaaaaaaaaaaaaa;

        printf("exit \n");

}

gcc -o correct correct.c

objdump -x correct | grep bss
