perf record: Handle argument change in sched_switch Recently sched_switch tracepoint added a new argument for prev_state, but it's hard to handle the change in a BPF program. Instead, we can check the function prototype in BTF before loading the program. Thus I make two copies of the tracepoint handler and select one based on the BTF info.
