Subject: [PATCH bpf-next v7 14/17] selftests/bpf: Update task_local_storage/task_storage_nodeadlock test
Date: Thu, 5 Feb 2026 14:29:12 -0800 [thread overview]
Message-ID: <20260205222916.1788211-15-ameryhung@gmail.com> (raw)
In-Reply-To: <20260205222916.1788211-1-ameryhung@gmail.com>
Adjust the error code we are checking against as
bpf_task_storage_delete() now returns -EDEADLK or -ETIMEDOUT when
deadlock happens.
