 * kernel_recvmsg - Receive a message from a socket (kernel space)

 * @sock:       The socket to receive the message from

 * @msg:        Received message

 * @vec:        Input s/g array for message data

 * @num:        Size of input s/g array

 * @size:       Number of bytes to read

 * @flags:      Message flags (MSG_DONTWAIT, etc...)

 *

 * On return the msg structure contains the scatter/gather array passed in the

 * vec argument. The array is modified so that it consists of the unfilled

 * portion of the original array.

 *

 * The returned value is the total number of bytes received, or an error.
