Subject: [PATCH v6 03/14] sched/deadline: Clear the defer params
Date: Wed, 2 Jul 2025 19:29:28 -0400 [thread overview]
Message-ID: <20250702232944.3221001-4-joelagnelf@nvidia.com> (raw)
In-Reply-To: <20250702232944.3221001-1-joelagnelf@nvidia.com>
The defer params were not cleared in __dl_clear_params. Clear them.
Without this is some of my test cases are flaking and the DL timer is
not starting correctly AFAICS.
Fixes: a110a81c52a9 ("sched/deadline: Deferrable dl server")
