Thank you for your concern. There are some question in my mind right 
now.
Should I trace user space triggering ? 
Will it be effective proposal for GSOC ?

As far if, I trace user space function till the system call then picture 
will be something :-

main() 	-> fun1() -> fun2() -> printf() 
					-syscall1();
					-syscall2();
					-syscall3(); 				      
			    -> scanf()
					-syscall6();
					-syscall9();			     
			    -> fork()
       					-syscall2();
					-syscall9();
					.....

	-> fun4() -> sum(); -> libfn()
					-syscall5();
 					-syscall5(); 
 					-syscall5(); 


       	-> fun5() -> exit()
			    - syscall();
			   .....


Should I working on it or it is already there into strace ?
Give me your valuable input regarding this.
