static atomic_t globalmem_available=ATOMIC_INIT(1);
//define one atomic available
spinlock_t globalmem_spin; //define spinlock
spin_lock_init(&globalmem_spin);

/home/MODULE/globalmem/globalmem-driver.c:33: 错误：expected identifier or ‘(’ before ‘while’
也就是最后一行出错了！
为什么spin_lock_init()会出现这个错误呢》？

spin_lock_init宏是个while循环，所以你要将其放到函数体内部去
