exporting symbols circular?

If moduleA exports symbols for moduleB ( using EXPORT_SYMBOL() )and moduleB exports symbols for moduleA, then no matter which order you load the modules, they will report ...

insmod: error inserting 'modA.ko': -1 Unknown symbol in module
insmod: error inserting 'modB.ko': -1 Unknown symbol in module

How can this be resolved?

May be modprobe will work ?


man insmod :
""insmod is a trivial program to insert a module into the kernel ..
Most users will want to use modprobe(8) instead, which is cleverer.""

That is using modprobe. The problem is not what tool is used to load them, but the dependencies of exports each module has from the other.
