Date: Mon, 06 Nov 2017 23:03:02 +0000 From: Ben Hutchings <ben@...adent.org.uk> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org CC: akpm@...ux-foundation.org, "Leon Romanovsky" <leon@...nel.org>, "Alex Vesker" <valex@...lanox.com> Subject: [PATCH 3.16 056/294] IB/ipoib: Prevent setting negative values to max_nonsrq_conn_qp 3.16.50-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Alex Vesker <valex@...lanox.com> commit 11f74b40359b19f760964e71d04882a6caf530cc upstream. Don't allow negative values to max_nonsrq_conn_qp. There is no functional impact on a negative value but it is logicically incorrect.
