Hi,
can we have:
commit 2ba3e6e8afc9b6188b471f27cf2b5e3cf34e7af2
Author: Theodore Ts'o <tytso@mit.edu>
Date: Wed Feb 15 01:26:39 2017 -0500
ext4: fix fencepost in s_first_meta_bg validation
in stable trees wherever 3a4b77cd47bb837b8557595ec7425f281f2ca1fe (ext4:
validate s_first_meta_bg at mount time) was applied? It fixes its
fallout as was reported by IBM to our bugzilla:
EXT4-fs (dm-0): mounting ext3 file system using the ext4 subsystem
EXT4-fs (dm-0): first meta block group too large: 1 (group descriptor
block count 1)
<8D>FAILED<D9> Failed to mount /sysroot/usr.
3.12 already has the patch as of 3.12.71.
thanks,

Added to 4.4 and 4.9-stable trees, thanks for catching this.
