The test is pretty simple; if the file is not getting created, it sounds like problem with the fallocate command. I'd suggest trying to run the commands in tests/generic/315 by hand, and seeing what's going wrong, but I'm pretty sure this is a configuration issue in your test environment. This is one of the reasons why I set up the xfstests-bld / kvm-xfstests infrastructure, BTW; it handles most of these setup issues for ext4 developers who otherwise might not end up using xfstests for regression testing. - Ted
