commit 1eb41a9a63803646aa746cc990d3ca7ada865c89
Author: Stephane Eranian <er...@gm...>
Date:   Fri Mar 2 18:50:21 2012 +0100

    preserve perf_event_attr initialization across library calls
    
    Callers may have already initialized certain fields inside
    the perf_event_attr struct pass to pfm_get_os_event_encoding()
    for perf_event. For instance, the attr->size field. It is
    important that the library preserve this field. The caller
    and library may have different versions of that struct.
    The library may not use all the fields inside perf_event_attr
    and therefore those should not be destroyed.
