From: Darrick J. Wong <djwong@xxxxxxxxxx> Nearly all of the reflink and fpunch/fcollapse/finsert tests that I have written assumed that it was ok to use 64k as the fundamental unit of allocation. This works fine for testing the XFS data device, since the file allocation unit is always a power of two, and never larger than 64k. Making this assumption allows those tests to encode md5sums in the golden output for easy file data integrity checking. Unfortunately, this isn't necessarily the case when we're testing reflink and fallocate on the XFS realtime device. For those configurations, the file allocation unit is a realtime extent, which can be any integer multiple of the block size. If the request length isn't an exact multiple of the allocation unit size, reflink and fallocate will fail due to alignment issues, so there's no point in running these tests. Assuming this edgecase configuration of an edgecase feature is vanishingly rare, let's just _notrun the tests instead of rewriting a ton of tests to do their integrity checking by hand.
