Artem Savkov	d6a8117253	selftests/bpf: BPF test_prog selftests for bpf_loop inlining ... Bugzilla: https://bugzilla.redhat.com/2137876 commit 0e1bf9ed2000c16fa8e0703e255a23d64a4adb27 Author: Eduard Zingerman <eddyz87@gmail.com> Date: Tue Jun 21 02:53:44 2022 +0300 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> Signed-off-by: Artem Savkov <asavkov@redhat.com>	2023-01-05 15:46:31 +01:00
