2.25.1
When perf-sched enables the call-graph recording, sample_type of dummy
event does not have PERF_SAMPLE_CALLCHAIN, timehist_check_attr() checks
that the evsel does not have a callchain, and set show_callchain to 0.
Currently perf sched timehist only saves callchain when processing
sched:sched_switch event, timehist_check_attr() only needs to determine
whether the event has PERF_SAMPLE_CALLCHAIN.
Before:
# perf sched record -g true
[ perf record: Woken up 0 times to write data ]
[ perf record: Captured and wrote 4.153 MB perf.data (7536 samples) ]
# perf sched timehist
Samples do not have callchains.

Code cleanup, replace strcmp(evsel__name(evsel, {NAME})) with
evsel__name_is() helper.

Well, its not building:
builtin-trace.c: In function ‘cmd_trace’:
builtin-trace.c:4919:90: error: macro "assert" passed 2 arguments, but takes just 1
4919 | assert(evsel__name_is(trace.syscalls.events.bpf_output), "__augmented_syscalls__");

I'll fix it, but please test build things next time.

Sorry. I compiled it in a new environment before. This environment does
not support bpf skel, and the modified part of the code is included in
HAVE_BPF_SKEL, so I did not find this problem when I compiled it in my
environment.
Thanks for the correction. will confirm whether the modified code is
actually compiled next time.
Thanks,
Yang
