I'm messing with it...first impression:
unable create tracepoint event sys_enter_mmap on cpu 4, err: -19
unable create tracepoint event sys_enter_mmap on cpu 5, err: -19
unable create tracepoint event sys_enter_mmap on cpu 6, err: -19
unable create tracepoint event sys_enter_mmap on cpu 7, err: -19
[...]
Unsurprising, this is a four-core system. The code reads:
> for_each_possible_cpu(cpu)
> enable_tracepoint_on_cpu(cpu, &attr, call, arg, type);
Maybe that needs to be for_each_online_cpu() instead?
