From 99558d203ceab980d74066daac4050609f5eccf4 Mon Sep 17 00:00:00 2001 From: David Howells Date: Mon, 25 Mar 2019 16:38:25 +0000 Subject: vfs: Convert virtio_balloon to use the new mount API Convert the virtio_balloon filesystem to the new internal mount API as the old one will be obsoleted and removed. This allows greater flexibility in communication of mount parameters between userspace, the VFS and the filesystem. See Documentation/filesystems/mount_api.txt for more information.
