This patch breaks perf-record/report that the number of samples can't be shown in pipe mode: # perf record -e cycles -aq sleep 1 ; perf report -n --sort comm,dso | sed '/%/q;d' ; \ perf record -e cycles -aq sleep 1 | perf report -n --sort comm,dso | sed '/%/q;d' 99.86% 11804 swapper [kernel.kallsyms] 91.57% swapper [kernel.kallsyms] ^^^^^^ number of samples missing Moving and changing the code at the same time make the patch unreviewable. So no clue that's the problem here. -Robert -- Advanced Micro Devices, Inc.
