Delyan Kratunov	04fcb5f9a1	selftests/bpf: Migrate from bpf_prog_test_run ... bpf_prog_test_run is being deprecated in favor of the OPTS-based bpf_prog_test_run_opts. We end up unable to use CHECK in most cases, so replace usages with ASSERT_* calls.

Andrii Nakryiko	d8e86407e5	selftests/bpf: Convert legacy prog load APIs to bpf_prog_load() ... Convert all the uses of legacy low-level BPF program loading APIs (mostly bpf_load_program_xattr(), but also some bpf_verify_program()) to bpf_prog_load() uses.

Alexei Starovoitov	ca06f55b90	bpf: Add per-program recursion prevention mechanism ... Since both sleepable and non-sleepable programs execute under migrate_disable add recursion prevention mechanism to both types of programs when they're executed via bpf trampoline.
