    Subject[PATCH 29/52] perf inject: Add --kallsyms parameter
    Date
    Let perf inject take --kallsyms parameter the same as
    perf script and perf report do. That is needed for
    decoding Instruction Trace data using a copy of
    /proc/kcore for the kernel object because the kallsyms
    path is used to locate that copy.
