Subject: selftests/bpf: Fix test_lsm on s390x
X-Git-Tag: v6.6.17~5509^2~92^2~50
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=207612eb12b912cad40c0299fefcabf3d6cc1f3f;p=platform%2Fkernel%2Flinux-rpi.git

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.
