50 在使用一个pkey之前，必须先用pkey_alloc()分配它。一个应用程序直接调用
55 pkey = pkey_alloc(0, PKEY_DISABLE_WRITE);
57 ret = pkey_mprotect(ptr, PAGE_SIZE, real_prot, pkey);
63 pkey_set(pkey, 0); // clear PKEY_DISABLE_WRITE
65 pkey_set(pkey, PKEY_DISABLE_WRITE); // set PKEY_DISABLE_WRITE again
67 现在，当它释放内存时，它也将释放pkey，因为它不再被使用了::
70 pkey_free(pkey);
85 pkey = pkey_alloc(0, PKEY_DISABLE_WRITE | PKEY_DISABLE_READ);
