Subject: [PATCH bpf-next v6 8/9] selftests/bpf: Make sure mount directory exists
Date: Tue, 26 Sep 2023 22:27:47 +0200 [thread overview]
Message-ID: <20230926202753.1482200-9-daan.j.demeyer@gmail.com> (raw)
In-Reply-To: <20230926202753.1482200-1-daan.j.demeyer@gmail.com>
The mount directory for the selftests cgroup tree might
not exist so let's make sure it does exist by creating
it ourselves if it doesn't exist.
