Should /proc/kallsyms contain the sys_call_table symbol?

I'm doing some research, and i've noticed an odd thing in my opinion:

1. According to all references, the /proc/kallsyms file contains all the
global kernel symbols, and those of the modules too. [ NOT just the
exported symbols like /proc/ksyms used to do in 2.4 kernels ]

2. Due to the above fact, the sys_call_table symbol should be inside it.


In ubuntu, it actually is there, it can be found with a grep.

BUT, i've tested also in Debian, Redhat el4, centos4, and fedora 9, and
the symbol is NOT inside the kallsyms file.

Can someone explain this behaviour? And, should this symbol be in there
or not?


Thanks,
John
