Here is the summary with links:
  - [bpf-next,1/2] bpf, cpumap: Use queue_rcu_work() to remove unnecessary rcu_barrier()
    https://git.kernel.org/bpf/bpf-next/c/8f8500a247c9
  - [bpf-next,2/2] bpf, cpumask: Clean up bpf_cpu_map_entry directly in cpu_map_free
    https://git.kernel.org/bpf/bpf-next/c/c2e42ddf26ca

You are awesome, thank you!
