From df7e40425813c50cd252e6f5e348a81ef1acae56 Mon Sep 17 00:00:00 2001 From: Yixian Liu Date: Mon, 19 Mar 2018 21:36:07 +0800 Subject: RDMA/hns: Fix init resp when alloc ucontext The data in resp will be copied from kernel to userspace, thus it needs to be initialized to zeros to avoid copying uninited stack memory.
