perf test: Record only user callchains on the "Check Arm64 callgraphs are complete in fp mode" test
The testcase 'Check Arm64 callgraphs are complete in fp mode' wants to see the following output: 610 leaf 62f parent 648 main However, without excluding kernel callchains, the output might look like: ffffc2ff40ef1b5c arch_local_irq_enable ffffc2ff419d032c __schedule ffffc2ff419d06c0 schedule ffffc2ff40e4da30 do_notify_resume ffffc2ff40e421b0 work_pending 610 leaf 62f parent 648 main Adding '--user-callchains' leaves only the wanted symbols in the chain.
