[so] [tema5] rezolvarea dilemei

[Silviu-Ionut Ganceanu]

Plusand, cred ca ce vream check_ram0 de fapt este:

static void check_ram0 (size_t ppages)
{
....
    for (i = 0; i < ppages * p_sz / 4; i++) {
        read (ram_fd, &read_val, 4);
        if (read_val != SWAP_POISON) {
            check = 0;
            break;
        }
    }

    test ("ram_clean", check);
}
