What's the right way to kill a process in Linux Kernel?

Question

What's the right way to kill a process in Linux Kernel, should I locate sys_kill and call it? (It looks rude)

P.S I have the task_struct and the pid of the target process

Answer 1

You can send the SIGKILL to the target process. thats a way to do it. But if there exists any userland solutions, i would never kill a process from kernel
