From 3203c9010060806ff88c9989aeab4dc8d9a474dc Mon Sep 17 00:00:00 2001 From: Kleber Sacilotto de Souza Date: Wed, 27 Jun 2018 17:19:21 +0200 Subject: test_bpf: flag tests that cannot be jited on s390 Flag with FLAG_EXPECTED_FAIL the BPF_MAXINSNS tests that cannot be jited on s390 because they exceed BPF_SIZE_MAX and fail when CONFIG_BPF_JIT_ALWAYS_ON is set. Also set .expected_errcode to -ENOTSUPP so the tests pass in that case.
