Hey guys,
I have a module which defines a specific print function, and another
module that uses said function. From the first module I have used
EXPORT_SYMBOL(function_1). From within the second module I would like to
rebind that function to another printing function, and once I'm
finished, rebind it back to the original function.
So in theory the pseudo-code would look something like this
module_1.c
function_1()
{
do some stuff
}
my_print_function = function_1
EXPORT_SYMBOL(my_print_function)
module_2.c
function_t()
{
doing different stuff
}
placeholder = my_print_function
my_print_fuction = function_2
<do some other stuff>
my_print_function = placeholder
<END OF CODE>
My question is: Is this the correct way of doing this? Or will this
cause issues?
