Eduard Zingerman	0e1bf9ed20	selftests/bpf: BPF test_prog selftests for bpf_loop inlining ... Two new test BPF programs for test_prog selftests checking bpf_loop behavior. Both are corner cases for bpf_loop inlinig transformation: - check that bpf_loop behaves correctly when callback function is not a compile time constant - check that local function variables are not affected by allocating additional stack storage for registers spilled by loop inlining Signed-off-by: Eduard Zingerman <eddyz87@gmail.com> Acked-by: Song Liu <songliubraving@fb.com> Link: https://lore.kernel.org/r/20220620235344.569325-6-eddyz87@gmail.com Signed-off-by: Alexei Starovoitov <ast@kernel.org>	2022-06-20 17:40:52 -07:00
