[biswa at nerdbox linux-2.6.20.4]$ nm vmlinux | grep kernel_execve
c01072ea T kernel_execve
[biswa at nerdbox linux-2.6.20.4]$ cat /proc/kallsyms | grep kernel_execve
c01072ea T kernel_execve

As 'kernel_execve' symbol is found on vmlinux and the same address
is reflected in kallsyms I believe it should have got exported.

But again, When I checked into Modules.symvars I could not find
kernel_execve in that.

How strange?

What can be the reason?

Thanks for your help
