Yes unsigned int is a better choice.

How does the following look?

struct ksft_count
{
unsigned int ksft_pass;
unsigned int ksft_fail;
unsigned int ksft_xfail;
unsigned int ksft_xpass;
unsigned int ksft_xskip;
};

static ksft_count ksft_cnt;

static inline void ksft_inc_pass_cnt(void) { ksft_cnt.ksft_pass++; }
static inline void ksft_inc_fail_cnt(void) { ksft_cnt.ksft_fail++; }
static inline void ksft_inc_xfail_cnt(void) { ksft_cnt.ksft_xfail++; }
static inline void ksft_inc_xpass_cnt(void) { ksft_cnt.ksft_xpass++; }
static inline void ksft_inc_xskip_cnt(void) { ksft_cnt.ksft_xskip++; }

With this approach, tests don't have to define their own counter
variable and pass it in. I am looking to abstract the framework
as much as possible.
