So let's use vmlinux.h directly. We could probably also extend bpf_tracing.h to work with kernel-defined pt_regs, just like we do for x86 (see __KERNEL__ and __VMLINUX_H__ checks). It's more work, but will benefit other end users, not just selftests. > > Signed-off-by: Pu Lehui <pulehui@xxxxxxxxxx> > --- > tools/testing/selftests/bpf/progs/loop1.c | 8 ++------ > tools/testing/selftests/bpf/progs/loop2.c | 8 ++------ > tools/testing/selftests/bpf/progs/loop3.c | 8 ++------ > tools/testing/selftests/bpf/progs/loop6.c | 20 ++++++------------- > .../selftests/bpf/progs/test_overhead.c | 8 ++------ > .../selftests/bpf/progs/test_probe_user.c | 6 +----- > 6 files changed, 15 insertions(+), 43 deletions(-) > [...]
