函数名称：do_proc_dointvec_ms_jiffies_conv

函数原型：static int do_proc_dointvec_ms_jiffies_conv(bool *negp, unsigned long *lvalp, int *valp, int write, void *data)

返回类型：int

参数：

类型参数名称
bool *negp
unsigned long *lvalp
int *valp
intwrite
void *data
3039  如果write则
3040  jif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
3042  如果jif大于INT_MAX则返回:1
3044  valp等于jif
3045  否则
3046  val等于valp
3048  如果val小于0则
3049  * negp = true
3050  lval等于负val
3051  否则
3052  * negp = false
3053  lval等于val
3055  lvalp等于Convert various time units to each other:
