From aa10d51f15ed2100e17d94802d69cb47352d79b6 Mon Sep 17 00:00:00 2001 From: Xie Yongji Date: Mon, 18 Jul 2022 16:50:12 +0800 Subject: [PATCH] fuse: Remove the control interface for virtio-fs [ Upstream commit 02850a869e1c347be236917749b772ee920d2c89 ] The commit cf6e9b4a2993 ("fuse: allow skipping control interface and forced unmount") tries to remove the control interface for virtio-fs since it does not support aborting requests which are being processed. But it doesn't work now. This patch fixes it by skipping creating the control interface if fuse_conn->no_control is set.
