SYS_TGKILL(9) Driver Basics SYS_TGKILL(9)

sys_tgkill - send signal to one specific thread
SYNOPSIS
long sys_tgkill(pid_t tgid, pid_t pid, int sig);
ARGUMENTS
tgid
the thread group ID of the thread
pid
the PID of the thread

This syscall also checks the tgid and returns -ESRCH even if the PID exists but it's not belonging to the target process anymore. This
method solves the problem of threads exiting and PIDs getting reused.
