Subject: [PATCH 08/13] habanalabs: allow unregistering eventfd when device non-operational
Date: Thu, 6 Oct 2022 11:23:03 +0300 [thread overview]
Message-ID: <20221006082308.1266716-8-ogabbay@kernel.org> (raw)
In-Reply-To: <20221006082308.1266716-1-ogabbay@kernel.org>
From: Tomer Tayar <ttayar@habana.ai>
Unregistering eventfd is for releasing host resources and doesn't
involve an access to the device. As such, there is no reason to disallow
it when device isn't operational.
