From 75d4e06f049ffb059fdf7e81c0c4c9fab2ba60e4 Mon Sep 17 00:00:00 2001 From: David Howells Date: Mon, 25 Mar 2019 16:38:24 +0000 Subject: vfs: Convert dax to use the new mount API Convert the dax 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.
