Subject: [Devel] [PATCH vz10] selftests: binderfs: skip the stress test without binderfs
Date: Tue, 1 Sep 2026 02:50:36 +0300 [thread overview]
Message-ID: <20260831235046.1651611-1-eva.kurchatova@virtuozzo.com> (raw)
binderfs_test_stress mounts binderfs 32 times and asserts on the first
mount, so on a kernel without CONFIG_ANDROID_BINDERFS the case fails
rather than reporting that the filesystem is not there.
Probe once with a mount into a temporary directory and skip when the
kernel answers ENODEV. Only ENODEV means the filesystem is missing;
anything else is a real failure and still fails, as does a temporary
directory we cannot create.

Feature: fix selftests
