函数名称：s_prime_number - test whether the given number is prime*@x: the number to test* A prime number is an integer greater than 1 that is only divisible by* itself and 1

函数原型：bool is_prime_number(unsigned long x)

返回类型：bool

参数：

类型参数名称
unsigned longx
226  _read_lock() - mark the beginning of an RCU read-side critical section* When synchronize_rcu() is invoked on one CPU while other CPUs* are within RCU read-side critical sections, then the* synchronize_rcu() is guaranteed to block until after all the other
227  p等于cu_dereference() - fetch RCU-protected pointer for dereferencing*@p: The pointer to read, prior to dereferencing* This is a simple wrapper around rcu_dereference_check().(primes)
228  当x大于等于sz循环
229  _read_unlock() - marks the end of an RCU read-side critical section.* In most situations, rcu_read_unlock() is immune from deadlock.* However, in kernels built with CONFIG_RCU_BOOST, rcu_read_unlock()
231  如果非expand_to_next_prime(x)则返回:slow_is_prime_number(x)
234  _read_lock() - mark the beginning of an RCU read-side critical section* When synchronize_rcu() is invoked on one CPU while other CPUs* are within RCU read-side critical sections, then the* synchronize_rcu() is guaranteed to block until after all the other
235  p等于cu_dereference() - fetch RCU-protected pointer for dereferencing*@p: The pointer to read, prior to dereferencing* This is a simple wrapper around rcu_dereference_check().(primes)
237  result等于st_bit - Determine whether a bit is set*@nr: bit number to test*@addr: Address to start counting from
238  _read_unlock() - marks the end of an RCU read-side critical section.* In most situations, rcu_read_unlock() is immune from deadlock.* However, in kernels built with CONFIG_RCU_BOOST, rcu_read_unlock()
240  返回:result
