** Description changed: 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.
