From 207612eb12b912cad40c0299fefcabf3d6cc1f3f Mon Sep 17 00:00:00 2001 From: Ilya Leoshkevich Date: Sat, 28 Jan 2023 01:06:34 +0100 Subject: [PATCH] selftests/bpf: Fix test_lsm on s390x Use syscall macros to access the setdomainname() arguments; currently the code uses gprs[2] instead of orig_gpr2 for the first argument.
