Type:unsigned long
Parameter:
Type | Parameter | Name |
---|---|---|
struct __kfifo * | fifo | |
void __user * | to | |
unsigned int | len | |
unsigned int | off | |
unsigned int * | copied |
245 | If esize != 1 Then |
250 | l = min - return minimum of two values of the same or compatible types*@x: first value*@y: second value(len, size - off) |
253 | If Value for the false possibility is greater at compile time(ret) Then ret = DIV_ROUND_UP(ret + len - l, esize) |
255 | Else |
257 | If Value for the false possibility is greater at compile time(ret) Then ret = DIV_ROUND_UP(ret, esize) |
