Bug Description
== SRU Justification ==
A regression was introduced where ext4_check_
called before s_gdb_count was initialized. This regression was
introduced to Xenial in 4.4.0-134. This is fixed by mainline commit
44de022c4382.
Commit 44de022c4382 was also cc'd to upstream stable. However, it has
not made it's way into Xenial via stable updates as of yet.
== Fix ==
44de022c4382 ("ext4: fix false negatives *and* false positives in ext4_check_
== Regression Potential ==
Low. This commit has been cc'd upstream stable, so it has had
additional upstream review.
