This patch introduces the C-language equivalents of the functions below:

- atomic operation:
void set_bit(int nr, volatile unsigned long *addr);
void clear_bit(int nr, volatile unsigned long *addr);
void change_bit(int nr, volatile unsigned long *addr);
int test_and_set_bit(int nr, volatile unsigned long *addr);
int test_and_clear_bit(int nr, volatile unsigned long *addr);
int test_and_change_bit(int nr, volatile unsigned long *addr);

I wonder why you did not make these functions take volatile
unsigned int * address argument?

Because they are defined to operate on arrays of unsigned long
