Subject: [PATCH 0/2] generic: Addition of new tests for extsize hints

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.
