From 25e62655c79395c596601a35805c3c7376d097b6 Mon Sep 17 00:00:00 2001 From: Parav Pandit Date: Tue, 22 May 2018 20:33:45 +0300 Subject: IB/core: Reduce the places that use zgid Instead of open coding memcmp() to check whether a given GID is zero or not, use a helper function to do so, and replace instances of memcpy(z,&zgid) with memset.
