The comment explains key terms and concepts, and includes a short signature by the programmer who authored the code./* * Check if we are over our maximum process limit, but be sure to * exclude root. This is needed to make it possible for login and * friends to set the per-user process limit to something lower * than the amount of processes root is running. -- Rik */ if (atomic_read(&p->user->processes) >= p->rlim.rlim_cur && !capable(CAP_SYS_ADMIN) && !capable(CAP_SYS_RESOURCE)) goto bad_fork_free;
