Title:
  kernel 4.15.0-44 cannot mount ext4 fs with meta_bg enabled

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Starting with kernel 4.15.0-44 ext4 filesystem with meta_bg feature
  enabled can no longer be mounted.

  Steps to reproduce:

  - create two empty file and setup loopback devices on these files
  dd if=/dev/zero of=/loop1 bs=1M count=50
  losetup /dev/loop1 /loop1
  dd if=/dev/zero of=/loop2 bs=1M count=50
  losetup /dev/loop2 /loop2

  - create a ext4 fs with meta_bg enabled on loop1:

  mkfs.ext4 -O ^resize_inode,+meta_bg /dev/loop1

  - create a ext4 fs without any options on loop2:

  mkfs.ext4 /dev/loop2

  - try to mount the filesystems

  mkdir /mnt/loop1
  mkdir /mnt/loop2
  mount /dev/loop1 /mnt/loop1
  mount /dev/loop1 /mnt/loop2

  
  Expected behaviour:
  All mounts succeed without error.

  Actual behaviour:

  root@xubu-18-04:~# mount /dev/loop1 /mnt/loop1
  mount: /mnt/loop1: mount(2) system call failed: Structure needs cleaning.
