Here is the summary with links:
  - [bpf,v5,1/3] bpf: Wait for an RCU tasks grace period before freeing trampoline progs
    https://git.kernel.org/bpf/bpf/c/0fb5751a6e41
  - [bpf,v5,2/3] bpf: Skip detached progs in trampoline images that are still in use
    https://git.kernel.org/bpf/bpf/c/17637e1a581a
  - [bpf,v5,3/3] selftests/bpf: Detach a trampoline prog while a task sleeps before it
    https://git.kernel.org/bpf/bpf/c/d5288c519bbd

You are awesome, thank you!
