    slides/kernel-driver-development-io-memory: Clarify a list of functions
    
    People not so used to the command line do not understand very well
    read[bwlq] and interpret that as an array. As these functions are
    actually quite fundamental, let's list them all one by one, it does not
    hurt, so that later uses of read[bwlq] are actually understood the right
    way.
