    perf evsel: Auto allocate resources needed for some methods · 4eed11d5
    Arnaldo Carvalho de Melo authored
    While writing the first user of the routines created from the ad-hoc
    routines in the existing builtins I noticed that the resulting set of
    calls was too long, reduce it by doing some best effort allocations.
    
    Tools that need to operate on multiple threads and cpus should pre-allocate
    enough resources by explicitely calling the perf_evsel__alloc_{fd,counters}
    methods.
