From 7896dfb0a6180beb51bf34b32c9427984cb052c4 Mon Sep 17 00:00:00 2001 From: Parav Pandit Date: Tue, 10 Jan 2017 17:51:48 +0000 Subject: [PATCH] rdmacg: Fixed uninitialized current resource usage Fixed warning reported by kbuild test robot. When reading current resource usage value, when no resources are allocated, its possible that it can report a uninitialized value for current resource usage. This fix avoids it by initializing it to zero as no resource is allocated.
