kernel how to know the module used by another ?

[freegnu]

hi all, when
cat /proc/modules
it will see some modules are used by another or not used?
but how the kernel know the module used by another?

[Raymond]

if one module export a symbol (usually a function), and another module use
that symbol, the kernel will know that when it insert the latter module.
