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.
