Instead of Tracepoint, this is based on kprobes (kprobe and kretprobe). So it can probe wherever -kprobes can probe (this means, all functions body except for __kprobes -functions). Unlike the Tracepoint based event, this can be added and removed +kprobes can probe (this means, all functions except those with +__kprobes/nokprobe_inline annotation and those marked NOKPROBE_SYMBOL). +Unlike the Tracepoint based event, this can be added and removed dynamically, on the fly. To enable this feature, build your kernel with CONFIG_KPROBE_EVENTS=y. -- 2.11.1
