From 0dcdf32e642df5b2f3a82d3ebd639322b147c0ca Mon Sep 17 00:00:00 2001 From: Tiwei Bie Date: Wed, 24 Oct 2018 17:39:48 +0800 Subject: [PATCH] vhost: initialize postcopy ufd properly Currently, postcopy_ufd is initialized to 0 implicitly, so fd 0 could be closed unexpectedly by vhost_backend_cleanup(). Fix this issue by initializing postcopy_ufd to -1 explicitly.
