[PATCH 29/52] perf inject: Add --kallsyms parameter

Adrian Hunter
2014-07-22T13:28:05Z

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.
