Here is the summary with links:
  - [v3,1/3] bpf: NUL-terminate replaced sysctl value
    https://git.kernel.org/bpf/bpf-next/c/a66e3b5bacf3
  - [v3,2/3] bpf: use kvfree() for replaced sysctl write buffer
    https://git.kernel.org/bpf/bpf-next/c/4c21b5927d43
  - [v3,3/3] bpf: Restore sysctl new-value from 1 to 0
    https://git.kernel.org/bpf/bpf-next/c/2566c3b24219

You are awesome, thank you!
