Subject: [PATCH v4 03/15] sched/deadline: Clear the defer params
Date: Tue, 17 Jun 2025 16:05:06 -0400 [thread overview]
Message-ID: <20250617200523.1261231-4-joelagnelf@nvidia.com> (raw)
In-Reply-To: <20250617200523.1261231-1-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")
