From: Zhengchao Shao <shaozhengchao@huawei.com> mainline inclusion from mainline-v6.10-rc1 commit af398bd0cb2151a581027a19bd995f72af2310ac category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IC914B Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i... -------------------------------- smc_hash_sk and smc_unhash_sk are only used in af_smc.c, so make them static and remove the output symbol. They can be called under the path .prot->hash()/unhash().
