From 50c81cdbc90c254957b32b854223845dc7a4adac Mon Sep 17 00:00:00 2001 From: Dmitry Tantsur Date: Wed, 6 May 2020 15:21:05 +0200 Subject: [PATCH] Mark more configuration options as reloadable I have only checked the main configuration options and two generic drivers, leaving everything else untouched. Added are options that is possible and makes sense to reload.
