Subject: [PATCH net-next 0/2] Further robustify putting BPF progs

This series addresses a potential issue reported to us by Jann Horn
with regards to putting progs. First patch moves progs generally under
RCU destruction and second patch refactors getting of progs to simplify
code a bit. For details, please see individual patches. Note, we think
that addressing this one in net-next should be sufficient.

Thanks!

Daniel Borkmann (2):
  bpf: generally move prog destruction to RCU deferral
  bpf: refactor bpf_prog_get and type check into helper
