| H A D | test_tracepoint.c | diff 3087c61ed2c48548b74dd343a5209b87082c682d Wed Jan 19 20:08:40 CST 2022 Yafang Shao <laoar.shao@gmail.com> tools/testing/selftests/bpf: replace open-coded 16 with TASK_COMM_LEN
As the sched:sched_switch tracepoint args are derived from the kernel,
we'd better make it same with the kernel. So the macro TASK_COMM_LEN is
converted to type enum, then all the BPF programs can get it through
BTF.
The BPF program which wants to use TASK_COMM_LEN should include the
header vmlinux.h. Regarding the test_stacktrace_map and
test_tracepoint, as the type defined in linux/bpf.h are also defined in
vmlinux.h, so we don't need to include linux/bpf.h again.
