-// Tracepoint attaches the given eBPF program to the tracepoint with the given
-// group and name. See /sys/kernel/debug/tracing/events to find available

-//
-//	Tracepoint("syscalls", "sys_enter_fork")

-// Note that attaching eBPF programs to syscalls (sys_enter_*/sys_exit_*) is
-// only possible as of kernel 4.14 (commit cf5f5ce).
