    perf evlist: Rename cpus to user_requested_cpus · 0df6ade7
    Ian Rogers authored
    evlist contains cpus and all_cpus. all_cpus is the union of the cpu maps
    of all evsels.
    
    For non-task targets, cpus is set to be cpus requested from the command
    line, defaulting to all online cpus if no cpus are specified.
    
    For an uncore event, all_cpus may be just CPU 0 or every online CPU.
    
    This causes all_cpus to have fewer values than the cpus variable which
    is confusing given the 'all' in the name.
    
    To try to make the behavior clearer, rename cpus to user_requested_cpus
    and add comments on the two struct variables.
