For a single process we should be able to do:
struct pid *pid = ( some value ... )
struct task_struct *task;
rcu_read_lock();
task = pid_task(pid);
if (task)
group_send_sig_info(sig, info, task);
rcu_read_unlock();
If it comes up very often that looks like an idiom
that would appreciate a helper function.
For process groups we must get a read_lock on the task_list_lock
because otherwise the atomicity guarantees of sending a signal
to a process group are broken.
