From 57b74c1b318625057398ccbe479a157507488d8c Mon Sep 17 00:00:00 2001
From: Carlos Llamas <cmllamas@google.com>
Date: Tue, 14 Dec 2021 05:58:48 +0000
Subject: [PATCH] selftests/binderfs: skip tests for unsupported kernels
Binderfs was first introduced in Linux 5.0 release, so we need to skip
these tests for older kernels. Also, we force a successful exit as the
current framework doesn't handle KSFT_SKIP return codes.
