    Subject[PATCH 12/13] perf report: Add --symbol-filter option
    Date
    From: Namhyung Kim <namhyung.kim@lge.com>

    Add new --symbol-filter command line option to set appropriate filter
    string.

    Its short version is missing as I couldn't find an ideal one and
    --filter option of perf record also has no short version.
