Subject: [PATCH rdma-next v1 2/7] IB/uverbs: Set IOVA on IB MR in uverbs layer
Date: Tue, 30 Jun 2020 12:39:11 +0300 [thread overview]
Message-ID: <20200630093916.332097-3-leon@kernel.org> (raw)
In-Reply-To: <20200630093916.332097-1-leon@kernel.org>
From: Yishai Hadas <yishaih@mellanox.com>
Set IOVA on IB MR in uverbs layer to let all drivers have it, this
includes both reg/rereg MR flows.
As part of this change cleaned-up this setting from the drivers that
already did it by themselves in their user flows.
Fixes: e6f0330106f4 ("mlx4_ib: set user mr attributes in struct ib_mr")
