Florent Revest	d6a6a55518	libbpf: Move BPF_SEQ_PRINTF and BPF_SNPRINTF to bpf_helpers.h ... These macros are convenient wrappers around the bpf_seq_printf and bpf_snprintf helpers. They are currently provided by bpf_tracing.h which targets low level tracing primitives. bpf_helpers.h is a better fit. The __bpf_narg and __bpf_apply are needed in both files and provided twice. __bpf_empty isn't used anywhere and is removed from bpf_tracing.h Reported-by: Andrii Nakryiko <andrii@kernel.org> Signed-off-by: Florent Revest <revest@chromium.org> Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Link: https://lore.kernel.org/bpf/20210526164643.2881368-1-revest@chromium.org	2021-05-26 10:45:41 -07:00
Song Liu	e8168840e1	selftests/bpf: Add test for bpf_iter_task_vma ... The test dumps information similar to /proc/pid/maps. The first line of the output is compared against the /proc file to make sure they match.
