Hao Luo 63d9b80dcf bpf: Introducte bpf_this_cpu_ptr() ... Add bpf_this_cpu_ptr() to help access percpu var on this cpu. This helper always returns a valid pointer, therefore no need to check returned value for NULL. Also note that all programs run with preemption disabled, which means that the returned pointer is stable during all the execution of the program.
