...ntroduce NOKPROBE_SYMBOL() macro which builds a kprobe blacklist in build time. The usage of this macro is similar to the EXPORT_SYMBOL, put the NOKPROBE_SYMBOL(function); just after the function definition. If CONFIG_KPROBES=y, the macro is expanded to the definition of a static data structure of kprobe_blackpoint which is initialized for the function and put the address of the data structure in the "_kprobe_blacklist" section. Since the data structures are not fully initialized by the macro (because there is no "size" information), those are re-initialized at boot time by using kallsym...

Currently the blacklist is maintained by hand in kprobes.c which is separated from the function definition and is hard to catch up the kernel update. To solve this issue, I've tried to implement new NOKPROBE_SYMBOL() macro for making kprobe blacklist at build time. Since the NOKPROBE_SYMBOL() macros can be placed right after the function is defined, it is easy to maintain. At this moment, I
