From: Geliang Tang Date: Thu, 9 Mar 2023 14:50:02 +0000 (+0100) Subject: mptcp: add ro_after_init for tcp{,v6}_prot_override X-Git-Tag: v6.1.21~37 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d283617f97e12c838f113ebf07d5c050aa7bde88;p=platform%2Fkernel%2Flinux-starfive.git mptcp: add ro_after_init for tcp{,v6}_prot_override commit 822467a48e938e661965d09df5fcac66f7291050 upstream. 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.
