+Subject: Revert "btrfs: add dmesg output for first mount and last unmount of a filesystem"
+
+From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
+
+This reverts commit a480eb262b178e2baffa758b9cd5bde2d8470287 which is
+commit 2db313205f8b96eea467691917138d646bb50aef upstream.
+
+As pointed out by many, the disk_super structure is NOT initialized
+before it is dereferenced in the function
+fs/btrfs/disk-io.c:open_ctree() that this commit adds, so something went
+wrong here.
+
+Revert it for now until it gets straightened out.
