redundancy of probe handlers generations

[Li Guanglei]

Hi,

Take a very simple example:

probe kernel.function("sys_read"), kernel.function("sys_write")
{
         log("here")
}

systemtap will generate two probe handlers with the names of probe_0 
and probe_1. But these two are in fact the same. Especially when the 
list of probe points grows large, a lot of redundant codes will be 
generated.
