We recently noticed this series has been marked as "Not Applicable" on
Patchwork.

It looks like we can apply these patches:

  $ git checkout netdev-net/master # 780aa1209f88
  $ git-pw series apply 539963
  Applying: mptcp: fix possible divide by zero
  Using index info to reconstruct a base tree...
  M       net/mptcp/protocol.c

  Falling back to patching base and 3-way merge...
  Auto-merging net/mptcp/protocol.c

  Applying: selftests: mptcp: clean tmp files in simult_flows

Git auto-resolves conflicts. Is it why it is considered as "Not
Applicable" or did we miss something else?

Do we just need to resend these patches after a rebase?

Thank you for maintaining net!

Cheers,
Matt
