3.15-stable review patch. If anyone has any objections, please let me know. ------------------ From: Namjae Jeon <namjae.jeon@xxxxxxxxxxx> 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.
