It's added when the module is loaded with insmod and removed when the
module is removed.
But you don't have to use EXPORT_SYMBOL. if you don't care about it,
every symbol, that is not static will be exportet.
Does this means EXPORT_SYMBOL() and declaring a function as non-static is same
....

If you want to check which symbols of your module are exported, check
/proc/kallsyms.
thanks Andi ,
But i wanted to see what special treament does these symbols get once we have
"EXPORT_SYMBOL()ed " them
Vs....
ones which are not exported and non static .....
