Subject: [PATCH rdma-next 11/12] RDMA/uverbs: Remove redundant check
Date: Sun, 24 Jun 2018 11:23:52 +0300 [thread overview]
Message-ID: <20180624082353.16138-12-leon@kernel.org> (raw)
In-Reply-To: <20180624082353.16138-1-leon@kernel.org>
From: Leon Romanovsky <leonro@mellanox.com>
kern_spec->reserved is checked prior to calling to
kern_spec_to_ib_spec_filter() and it makes this second check redundant.
