From: Arnaldo Carvalho de Melo <acme@redhat.com>
One of the branches leading to an error had no debug message emitted, fix it, the new lines are:
# perf test -v kallsyms <SNIP> 0xffffffff81001000: diff name v: xen_hypercall_set_trap_table k: hypercall_page 0xffffffff810691f0: diff name v: try_to_free_pud_page k: try_to_free_pmd_page <SNIP> 0xffffffff8150bb20: diff name v: wakeup_expire_count_show.part.5 k: wakeup_active_count_show.part.7 0xffffffff816bc7f0: diff name v: phys_switch_id_show.part.11 k: phys_port_name_show.part.12 0xffffffff817bbb90: diff name v: __do_softirq k: __softirqentry_text_start <SNIP>
This in turn exercises another bug, still under investigation, because those aliases _are_ in kallsyms, with the same name...
