The kernel scheduler manages a list of tasks to run, known as a run queue.

Atomic atomic_read、atomic_set、atomic_add、atomic_sub WRITE_ONCE(x,val) tatic __always_inline void __write_once_size(volatile void *p, void *res, int size) { //簡單變數之Atomic由MESI協定來確保 switch (size) { case 1: *(volatile __u8 *)p = *(__u8 *)res; break;
