I had to send around 5 or 6 indication to user asynchronously .Using kill_fasync,it is possible to send only SIGIO signal which will solve only one indication.In this case what shall I do?? If 3 or 4 process running in user space,how to send to specific process ie., If iam sending a signal to user space having two or more process running,which process will receive that signal??
