Subject: [PATCH 6/6] ext4/242: Add ext4 specific test for fallocate zero range
This is copy of xfs/242. However it's better to make it file system
specific because the range can be zeroes either directly by writing
zeroes, or converting to unwritten extent, so the actual result might
differ from file system to file system.
