Subject: [PATCH AUTOSEL 4.14 045/103] RDMA/core: Follow correct unregister order between sysfs and cgroup
Date: Fri,  8 Nov 2019 06:42:10 -0500
Message-ID: <20191108114310.14363-45-sashal@kernel.org> (raw)
In-Reply-To: <20191108114310.14363-1-sashal@kernel.org>

From: Parav Pandit <parav@mellanox.com>

[ Upstream commit c715a39541bb399eb03d728a996b224d90ce1336 ]

During register_device() init sequence is,
(a) register with rdma cgroup followed by
(b) register with sysfs

Therefore, unregister_device() sequence should follow the reverse order.
