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
...
