[PATCH net 6/7] mptcp: add ro_after_init for tcp{,v6}_prot_override
From: Matthieu Baerts <hidden>
Date: 2023-02-27 17:30:34
Also in:
linux-kselftest, lkml, mptcp, stable
Subsystem:
networking [general], networking [mptcp], the rest · Maintainers:
"David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Matthieu Baerts, Mat Martineau, Linus Torvalds
From: Geliang Tang <redacted>
Add __ro_after_init labels for the variables tcp_prot_override and
tcpv6_prot_override, just like other variables adjacent to them, to
indicate that they are initialised from the init hooks and no writes
occur afterwards.
Fixes: b19bc2945b40 ("mptcp: implement delegated actions")
Cc: stable@vger.kernel.org
Fixes: 51fa7f8ebf0e ("mptcp: mark ops structures as ro_after_init")
