From 1588ab5d0b96301b893d63aa342faad0e37a02ff Mon Sep 17 00:00:00 2001 From: Alberto Garcia Date: Thu, 18 Feb 2016 12:27:00 +0200 Subject: throttle: Use throttle_config_init() to initialize ThrottleConfig We can currently initialize ThrottleConfig by zeroing all its fields, but this will change with the new fields to define the length of the burst periods. This patch introduces a new throttle_config_init() function and uses it to replace all memset() calls that initialize ThrottleConfig directly.
