From 1a6e9e76b713d9632783efe78295ed3507fdad64 Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Mon, 20 May 2019 13:44:57 +0100 Subject: device-dax: Drop register_filesystem() The device-dax fs is only there to allocate a common inode for each device-node that refers to the same device by major:minor. It is otherwise not user mountable and need not be displayed in /proc/filesystems.
