Title:
  regression with EXT4 file systems and meta_bg flag

Status in linux package in Ubuntu:
  In Progress
Status in linux source package in Xenial:
  In Progress

Bug description:
  Hello,

  In 16.04 lts (Ubuntu 4.4.0-134.160-generic 4.4.140) with all
  partitions in ext4 with flag meta_bg :

  kernel: [ 1905.799557] EXT4-fs (dm-7): ext4_check_descriptors: Block bitmap 
for group 0 overlaps block group descriptors
  kernel: [ 1905.799858] EXT4-fs (dm-7): group descriptors corrupted!

  Go back with the kernel 4.4.0-133-generic and all partitions mount
  correctly.

  It looks like this:

  The patch is available in 4.4.147 (https://lwn.net/Articles/762083/)
