Process 我的解决方案是否满足互斥的要求

为了满足互斥性，我写了两个过程，但我不确定是否是。。 我的初始标志值是0

process 1
while(1){

while flag=1 do{-nothing-}

flag=1

-enter critical section-

flag=0

}

process 2
while(1){

while flag=1 do{-nothing-}

flag=1

-enter critical section-

flag=0

}

事实上，它们完全一样。 这两个过程是否满足互斥性？ 我看不出违反了什么要求

Process 1                            Process 2

check if flag is 0 - it is
                                          check if flag is 0 - it is
set flag to 1
                                          set flag to 1        

At that point both processes are in their critical sections.
