trying to send signal from linux module
I have a kernel (linux 18.104.22.168) module.
I want this module, upon recieving an interrupt, to send a signal to a user process. How do i do that?
The module recives the pid of the user process via its proc file.
This dosent seem to work, any other ideas?
struct task_struct *p;
p = find_task_by_pid(pid_of_client);
the int pid_of_client is correct..
