perf tools: Asprintf like functions to format integer filter expression
char *asprintf_expr_in_ints(const char *var, size_t nints, int *ints);
char *asprintf_expr_not_in_ints(const char *var, size_t nints, int *ints);
Example of output formatted with those functions:
# ./tp_filter 6 12 2015
asprintf_expr_in_ints: id == 6 || id == 12 || id == 2015
asprintf_expr_not_in_ints: id != 6 && id != 12 && id != 2015
#
It'll be used with, for instance, perf_evsel__set_filter_in_ints(), that
will be used in turn to ask the kernel to filter out all raw_syscalls:*
except for the ones specified by the user via:
$ perf trace -e some,list,of,syscalls
