Subject: perf evlist: Do not pass struct record_opts to perf_evlist__prepare_workload()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=119fa3c922ff53a334507e198b2e3c66e99f54dc;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

perf evlist: Do not pass struct record_opts to perf_evlist__prepare_workload()

Since it's only used for checking ->pipe_output, we can pass the result
directly.

Now the perf_evlist__prepare_workload() don't have a dependency of
struct perf_record_opts, it can be called from other places like perf
stat.
