This test is basically to check the functionality of setting extsize hints for xfs filesystem through an ioctl. It covers various scenarios like setting and then getting extsize hints for various types of files like an empty file, non-empty file (with delayed allocation and allocated extents). This test set also tests one of scenarios where setting extsize hints on files with delayed allocated (incorrectly) succeeds and there is an ongoing patch series[1] that fixes it. Currently this test only runs in xfs but there is an patch series[2] in review that adds support for the extsize hints for ext4 as well. I have tested it on ppc64le (with page size 64k) and x86_64 (with page size 4k). The block sizes I have tested with are 2k, 4k, 8k, 16k, 64k with extsize being twice of the block size. I had to enable CONFIG_TRANSPARENT_HUGEPAGE to enable block size greater than 4k on x86_64.
