Subject: [NET]: New sysctls should use __read_mostly tags
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6dea649a8a4c4b086227018c919298f988c34b30;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

net_msg_warn should be placed in the read_mostly section, to avoid
performance problems on SMP
