Subject: [net-next 0/2] BPF, kprobes: Add current_in_cgroup helper

This patchset includes a helper and an example to determine whether the kprobe 
is currently executing in the context of a specific cgroup based on a cgroup
bpf map / array. 

Sargun Dhillon (2):
  bpf: Add bpf_current_in_cgroup helper
  samples/bpf: Add example using current_in_cgroup
