SystemTap support for different version of the kernel

[Hien Nguyen]

How do we provide support for different version of the kernel?

For example, RHEL4 has kernel 2.6.9-xx, and FC4 has kernel 2.6.12-xx. I 
wrote a script and tested on  FC4 , it worked fine, but it was not 
compiled on RHEL since I am using embedded C function and accessing the 
inet_sock struct, which is different between  2.6.9 and 2.6.12. To 
access to 'daddr' on
2.6.9  inet_sock->inet.daddr
vs
2.6.12 inet_sock->daddr

So when we write  tapset, should we provide multiple versions that 
support different kernels?
