Message-ID: <20171202155204.7691-27-alexander.levin@verizon.com> Date: Sat, 2 Dec 2017 15:52:26 +0000 From: alexander.levin@...izon.com To: "linux-kernel@...r.kernel.org" <linux-kernel@...r.kernel.org>, "stable@...r.kernel.org" <stable@...r.kernel.org> Cc: Majd Dibbiny <majd@...lanox.com>, Leon Romanovsky <leon@...nel.org>, "Doug Ledford" <dledford@...hat.com>, alexander.levin@...izon.com Subject: [PATCH AUTOSEL for 4.9 27/33] IB/mlx5: Assign send CQ and recv CQ of UMR QP From: Majd Dibbiny <majd@...lanox.com> [ Upstream commit 31fde034a8bd964a5c7c1a5663fc87a913158db2 ] The UMR's QP is created by calling mlx5_ib_create_qp directly, and therefore the send CQ and the recv CQ on the ibqp weren't assigned. Assign them right after calling the mlx5_ib_create_qp to assure that any access to those pointers will work as expected and won't crash the system as might happen as part of reset flow.
