perf probe: Add --funcs to show available functions in symtab
Add --funcs to show available functions in symtab. Originally this feature came from Srikar's uprobes patches ( http://lkml.org/lkml/2010/8/27/244 ) e.g. ... __ablkcipher_walk_complete __absent_pages_in_range __account_scheduler_latency __add_pages __alloc_pages_nodemask __alloc_percpu __alloc_reserved_percpu __alloc_skb __alloc_workqueue_key __any_online_cpu __ata_ehi_push_desc ... This also supports symbols in module, e.g. ... cleanup_module cpuid_maxphyaddr emulate_clts emulate_instruction emulate_int_real emulate_invlpg emulator_get_dr emulator_set_dr emulator_task_switch emulator_write_emulated emulator_write_phys fx_init ...
