Subject: [PATCH] selftests/futex: skip tests if shmget unsupported
Date: Thu, 16 Oct 2025 16:19:41 +0000 [thread overview]
Message-ID: <20251016162009.3270784-1-cmllamas@google.com> (raw)
On systems where the shmget() syscall is not supported, tests like
anon_page and shared_waitv will fail. Skip these tests in such cases to
allow the rest of the test suite to run.
