[ Upstream commitfe3300897c] Currently, open() is called from the user program and it calls the syscall 'sys_openat', not the 'sys_open'. This leads to an error of the program of user side, due to the fact that the counter maps are zero since no function such 'sys_open' is called. This commit adds the kernel bpf program which are attached to the tracepoint 'sys_enter_openat' and 'sys_enter_openat'.
