Hi, All,
I have a question for ftrace usage. It is that if I have a function A, then I
want to
know how function A is ivoked?
I know ftrace can show me what sub-functions that A called by below steps:
# echo function_graph > current_tracer
# echo function_A > set_graph_function
# cat trace
Then a call stack will show what functions A has called. But sometimes I want
to
know how A is called. Is there a method to do this? Please help me!Regards and Thanks! Du, Changbin
