description

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.
