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 user 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.

Since you are the patch's author, it's not necessary to add your
tested tag.
