Can I use any signals in asynchronous notification?
 

Can I use any signal aside from SIGIO in asynchronous notification in the kernel space? I have read the chapter 6: advance char drivers, of linux device drivers 3rd edition, and it only states that SIGIO is the signal to use... I think it will have conflict if I have multitasking and all of my tasks need asynchronous signals, but I dont want all of them to execute when a SIGIO is signalled. So I thought of using different signals for each tasks so that each will execute independently.
