File perf-pmu-change-convert_scale-from-static-to-global.patch of Package perf.23962
From: Jin Yao <yao.jin@linux.intel.com> Date: Wed, 28 Aug 2019 13:59:29 +0800 Subject: perf pmu: Change convert_scale from static to global Git-commit: a55ab7c4ca6986a542d313b02043a39ebf712a39 Patch-mainline: v5.4-rc1 References: jsc#SLE-13661 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.
