Subject: [net 1/4] net/mlx5: Fix function calculation for page trees
Date: Mon, 1 Feb 2021 23:07:00 -0800 [thread overview]
Message-ID: <20210202070703.617251-2-saeed@kernel.org> (raw)
In-Reply-To: <20210202070703.617251-1-saeed@kernel.org>
From: Daniel Jurgens <danielj@nvidia.com>
The function calculation always results in a value of 0. This works
generally, but when the release all pages feature is enabled it will
result in crashes.
Fixes: 0aa128475d33 ("net/mlx5: Maintain separate page trees for ECPF and PF functions")
