Hi.
More than 2 years ago I wrote a small non-portable patch [1] to gather
some statistics
about keyboard usage[2] ( I show the counters with modulo 10 but still this is a
security risk. Perhaps some random noise should be added ).
[1]
http://svn.arhuaco.org/svn/src/pcgotchi/trunk/proc-keystroke
struct sarpic_dev *dev = filep->private_data;
int ret_val;
if (down_interruptible (&dev->sem))
return -ERESTARTSYS;
ret_val = __kfifo_put_user(dev->fifo, buffer, length);
up(&dev->sem);
wake_up_interruptible(&dev->readq);
return ret_val;
}

Hi Stelian.
I'm sending the new patch without kfifo_put_user and kfifo_get_user.
