perf tools: Only display parent field if explictly sorted
We don't need to display the parent field if the parent sorting machinery is only used for parent filtering (as in "-p foo"). However if parent filtering is used in combination with explicit parent sorting ( -s parent), we want to display it. Result with: perf report -p kernel_thread -s parent Before: # Overhead Parent symbol # ........ ............. # 0.07% | --- ioread8 ata_sff_check_status ata_sff_tf_load ata_sff_qc_issue ata_bmdma_qc_issue ata_qc_issue ata_scsi_translate ata_scsi_queuecmd scsi_dispatch_cmd scsi_request_fn __blk_run_queue __make_request generic_make_request submit_bio submit_bh journal_submit_commit_record jbd2_journal_commit_transaction kjournald2 kthread kernel_thread_helpe After: # Overhead Parent symbol # ........ ............. # 0.07% kernel_thread_helper | --- ioread8 ata_sff_check_status ata_sff_tf_load ata_sff_qc_issue ata_bmdma_qc_issue ata_qc_issue ata_scsi_translate ata_scsi_queuecmd scsi_dispatch_cmd scsi_request_fn __blk_run_queue __make_request generic_make_request submit_bio submit_bh journal_submit_commit_record jbd2_journal_commit_transaction kjournald2 kthread kernel_thread_helper Signed-off-by: Frederic Weisbecker <fweisbec@gmail.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Stephane Eranian <eranian@google.com> Cc: David Ahern <dsahern@gmail.com> Cc: Sam Liao <phyomh@gmail.com>
