__kfifo_put - puts some data into the FIFO, no locking version
unsigned int __kfifo_put (struct kfifo * fifo, unsigned char * buffer,
unsigned int len);
fifo the fifo to be used.
buffer the data to be added.
len the length of the data to be added.
This function copies at most ’len’ bytes from the ’buffer’ into the
FIFO depending on the free space, and returns the number of bytes
Note that with only one concurrent reader and one concurrent writer,
you don’t need extra locking to use these functions.
