Feng Tang 1500b93b61 perf symbols: Filter samples with unresolved symbol when "--symbols" option is used ... Report/top commands support to only handle specific symbols with "--symbols" option, but current code will keep those samples whose symbol can't be resolved, which should actually be filtered. If we run following commands: $perf record -a tree $perf report --symbols intel_idle -n the output will be: Without the patch: ================== 46.27% 156 sshd [unknown] 26.05% 48 swapper [kernel.kallsyms] 17.26% 38 tree libc-2.12.1.so 7.69% 17 tree tree 2.73% 6 tree ld-2.12.1.so With the patch: =============== 100.00% 48 swapper [kernel.kallsyms] Signed-off-by: Feng Tang <feng.tang@intel.com> Cc: Andi Kleen <andi@firstfloor.org> Cc: David Ahern <dsahern@gmail.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Link: http://lkml.kernel.org/r/1347007349-3102-2-git-send-email-feng.tang@intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>		2012-09-17 13:10:57 -03:00
