      // entry. Note that the call to ftruncate below will change the file size but

      // will not allocate space on disk and this call to fallocate will not

      // change the file size.

      // Note: fallocate is only supported by the following filesystems -

      // btrfs, ext4, ocfs2, and xfs. Therefore fallocate might fail with

      // EOPNOTSUPP error when issued in other filesystems.

      // Hence, check for the return error code before concluding that the

      // disk does not have enough space.
