commit 3aa2fe6d19a35a2da26f0b7ead726d9bc8bf7cd8
Author: Maynard Johnson <may...@us...>

    oprofile pp tools should print messages about lost samples
    
    When operf completes running, it collects statistics about
    lost samples, records them in the operf.log, and prints
    a warning message if the number of lost samples exceeds
    a pre-defined percentage (.01%) of the total number of
    samples.  However, when opreport or any of the other oprofile
    post-processing tools are run, the statistics are not
    readily available (only in the operf.log), so there is no
    warning about lost samples. This patch persists those
    statistics to files in the <session-dir>/samples/current/stats
    dir, allowing the pp tools to access them later.  These
    stats files are also copied by oparchive, so even archived
    profile data will have the statistics available.
