Subject: [PULL 03/30] libvhost-user: remove watch for kick_fd when de-initialize vu-dev
Date: Fri, 9 Oct 2020 20:35:02 +0100

From: Coiby Xu <coiby.xu@gmail.com>

When the client is running in gdb and quit command is run in gdb,
QEMU will still dispatch the event which will cause segment fault in
the callback function.
