Hi,
I have written a kernel module, and i want to call a function
that belongs to my module from the native kernel module function say
vfs_write().
If you want vfs_write (built into the kernel image) to be able to call
a function, that function should be built into the kernel image as
well (since the kernel is a monolithic statically compiled binary).
In other words, if you want to call your kernel module function A from
another function B, you need to:
1) EXPORT_SYMBOL(A)
2) Make sure B is built in as kernel module as well.
2) Load module containing A before module containing B.
Thanks,
Rajat
