    md/linear: use call_rcu to free obsolete 'conf' structures. · 495d3573

    Current, when we update the 'conf' structure, when adding a
    drive to a linear array, we keep the old version around until
    the array is finally stopped, as it is not safe to free it
    immediately.
    
    Now that we have rcu protection on all accesses to 'conf',
    we can use call_rcu to free it more promptly.
