From 5292443431fff5ba20f1b48985d382dd824016eb Mon Sep 17 00:00:00 2001 From: Steve Wise Date: Thu, 1 Mar 2018 13:58:20 -0800 Subject: [PATCH] mlx4_ib: zero out struct ib_pd when allocating Zero out the fields of the struct ib_pd for user mode pds so that users querying pds via nldev will not get garbage. For simplicity, use kzalloc() to allocate the mlx4_ib_pd struct.
