Hi Geunsik,
Thanks for your patch. But Kernel upstream: struct perf_event * perf_event_create_kernel_counter(struct perf_event_attr *attr, int cpu, struct task_struct *task, perf_overflow_handler_t overflow_handler, void *context)
I am sorry that gtp.patch is just for the Kernel upstream (Actually, it just for review).
I suggest you use LKM if it is OK for you.
If you want include KGTP into your kernel tree or something, maybe I can supply a special patch for you.
BTW looks I need release an gtp_auto.patch that can patch to most of Linux kernel.
Thanks, Hui
