evsel->system_wide is introduced by commit bf8e8f4b832972c76d64ab2e2837 (perf evlist: Add 'system_wide' option), which is used for mixing evsels that aren't system-wide with ones that are [1]. However, for global system wide recording (perf record -a ...), evsel->system_wide is set to false, which is confusion.
This patch set evsel->system_wide to true if the target.system_wide is set, which makes evsel->system_wide a reliable way to describe whether itself is system_wide or not.
