Let me compile the upstream codes on CentOS7 again. Well, I see a potential problem even in the upstream, but it's only when CONFIG_LTO is set. However, CONFIG_LTO isn't used any other places (or even set) in the upstream tree yet, so the issue must not happen there. And yet, even if CONFIG_LTO is enabled, the first place to be fixed is rather in include/linux/init.h, not each code calling module_init() without a terminator semicolon. There are lots of such codes in the tree, and calls of init/exit without semicolon are official ways. Though, having semicolons looks nicer nowadays, so it'd make sense to add semicolons in the end. If so, we may fix all of them in a shot by a script.

It is good news that there is no real issue on upstream.

Let me compile the upstream codes on CentOS7 again. Well, I see a potential problem even in the upstream, but it's only when CONFIG_LTO is set. However, CONFIG_LTO isn't used any other places (or even set) in the upstream tree yet, so the issue must not happen there. And yet, even if CONFIG_LTO is enabled, the first place to be fixed is rather in include/linux/init.h, not each code calling module_init() without a terminator semicolon. There are lots of such codes in the tree, and calls of init/exit without semicolon are official ways. Though, having semicolons looks nicer nowadays, so it'd make sense to add semicolons in the end. If so, we may fix all of them in a shot by a script.
