commit cbe805c2122b8b46b1fbe7c6b1d8f69cd22fb901
Author: Marin Ramesa <address@hidden>

    track the console buffer usage with a boolean instead of an int
    
    A variable that keeps track of the console buffer usage should never receive
    values other than 0 and 1, so constrain it's value range to boolean. Plus, 
it's
    more readable this way.
    
    * device/cons.c (consbufused): Use boolean_t instead of an int.
