Ever wondered what actually happens when you use '@ = count()' in bpftrace?
What's happening when you use the hist or any other internal call? How many
bpf maps are used and how much you slow down the system? I'll describe the
bpftrace constructs and how they are translated to eBPF instructions. I'll also
introduce some of the new features like BTF support.
