I suspect the actual failure was due to
not being able to create a 1T sparse file
on an ext2 file system with 1K block size.
So I'm going to push this...

    tests: fiemap-perf: avoid a false failure on ext2

    * tests/cp/fiemap-perf: Skip the test on ext2 file systems,
    as we do for ext3.  Also skip the test if we can't create
    a 1TiB file, which can happen on ext2 for example where
    the sparse file size limit is lower than that of ext4.
