The only remaining function callable outside of kernel/fork.c is _do_fork(). It doesn't really follow the naming of kernel-internal syscall helpers as Christoph righly pointed out. Switch all callers and references to kernel_clone() and remove _do_fork() once and for all.
My only concern is around return type. long, int, pid_t ... can we choose one and stick to it? pid_t is probably the right return type within the kernel, despite the return type of clone3(). It'll save us some work if we ever go through the hassle of growing pid_t beyond 31-bit.
