Xiangyang Zhang c524f4cfb3 tracing/kprobes: 'nmissed' not showed correctly for kretprobe ... commit dfea08a2116fe327f79d8f4d4b2cf6e0c88be11f upstream. The 'nmissed' column of the 'kprobe_profile' file for kretprobe is not showed correctly, kretprobe can be skipped by two reasons, shortage of kretprobe_instance which is counted by tk->rp.nmissed, and kprobe itself is missed by some reason, so to show the sum.
