unsigned int?

It would probably make sense to have the counters in a structures,
something like: struct ksft_counter { ... } ksft_cnt;
Then just pass it around the proposed functions as arguments. That also
minimizes a bit the global variables and would allow you to easily
change it in the future.

Same here, just do:
static inline void ksft_print_cnts(struct ksft_counter counters)
{
...
}
Otherwise looks good.
