From dad4f19431653abf2a576ed062f8de4223eb228b Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Thu, 24 Sep 2020 16:15:40 +0100 Subject: [PATCH] util/vhost-user-server: drop unnecessary watch deletion Explicitly deleting watches is not necessary since libvhost-user calls remove_watch() during vu_deinit(). Add an assertion to check this though.
