    rbd: add an rbd features field · 34b13184
    Alex Elder authored
    Record the features values for each rbd image and each of its
    snapshots.  This is really something that only becomes meaningful
    for version 2 images, so this is just putting in place code
    that will form common infrastructure.
    
    It may be useful to expand the sysfs entries--and therefore the
    information we maintain--for the image and for each snapshot.
    But I'm going to hold off doing that until we start making
    active use of the feature bits.
