| |
From: Jin Yao <yao.jin@linux.intel.com>
The function convert_scale() can be used to convert string to unit and scale. For example,
s = "6000000000ns"; convert_scale(s, &unit, &scale);
unit = "ns", scale = 6000000000.
Currently this function is static. This patch renames the function to perf_pmu__convert_scale and changes the function to global. No functional change.
