From eae6e70cea2fd62a7ab2b3a6693d015e9d3d7fcc Mon Sep 17 00:00:00 2001 From: Jianfeng Tan Date: Mon, 12 Feb 2018 03:20:28 +0000 Subject: [PATCH] net/virtio-user: fix interrupts with kernel vhost intr_handle->fd was wrongly initialized as 0 (usually as the stdio fd) when virtio-user is used with vhost-kernel. So the interrupt thread might wrongly treat stdin events as LSC interrupts.
