函数名称：bfq_fifo_expire_sync_store

函数原型：static ssize_t bfq_fifo_expire_sync_store(struct elevator_queue *e, const char *page, size_t count)

返回类型：ssize_t

参数：

类型参数名称
struct elevator_queue *e
const char *page
size_tcount
6639  bfqd等于elevator_data
6639  __min等于1, __max等于0U的反右移1位
6639  ret等于bfq_var_store( & __data, (page))
6639  如果ret则返回:ret
6639  如果__data小于__min则__data等于__min
6639  否则如果__data大于__max则__data等于__max
6639  如果2恒等于1则** Timeout for async/sync requests; when it fires, requests * are served in fifo order.[1]等于msecs_to_jiffies: - convert milliseconds to jiffies*@m: time in milliseconds* conversion is done as follows:* - negative values mean 'infinite timeout' (MAX_JIFFY_OFFSET)* - 'too large' values [that would result in larger than
6639  否则如果2恒等于2则** Timeout for async/sync requests; when it fires, requests * are served in fifo order.[1]等于__data乘1000000L
6639  否则** Timeout for async/sync requests; when it fires, requests * are served in fifo order.[1]等于__data
6639  返回:count
