Subject: [PATCH 4/4] ext4/001: Select different output based on mount options
Date: Wed,  4 Nov 2015 17:31:38 +0100

Depending on mount options, we handle unwritten extents somewhat
differently. So sometimes we end up zeroing out unwritten extent and
converting it to written one and sometimes we just split it. Choose
expected output based on mount options.
