Subject: ext4: fix ZERO_RANGE test failure in data journalling
From: Namjae Jeon <[email protected]>
commit e1ee60fd89670da61b0a4bda59f8ffb2b8abea63 upstream.
xfstests generic/091 is failing when mounting ext4 with data=journal.
I think that this regression is same problem that occurred prior to collapse
range issue. So ZERO RANGE also need to call ext4_force_commit as
collapse range.
