Subject: [PATCH rdma-next v2 3/7] RDMA/core: Remove protection from wrong in-kernel API usage
Date: Tue, 3 Aug 2021 21:20:34 +0300 [thread overview]
Message-ID: <b9b9e981d1af148b750750196e686199dbbf61f8.1628014762.git.leonro@nvidia.com> (raw)
In-Reply-To: <cover.1628014762.git.leonro@nvidia.com>
From: Leon Romanovsky <leonro@nvidia.com>
The ib_create_named_qp() is kernel verb that is not used for user
supplied attributes. In such case, it is ULP responsibility to provide
valid QP attributes.
In-kernel API shouldn't check it, exactly like other functions that
don't check device capabilities.
