From: "Darrick J. Wong"<djwong@xxxxxxxxxx> Simple tests of various atomic write requests and a (simulated) hardware device. The first test performs basic multi-block atomic writes on a scsi_debug device with atomic writes enabled. We test all advertised sizes between the atomic write unit min and max. We also ensure that the write fails when expected, such as when attempting buffered io or unaligned directio. The second test is similar to the one above, except that it verifies multi-block atomic writes on actual hardware instead of simulated hardware. The device used in this test is not required to support atomic writes. The final two tests ensure multi-block atomic writes can be performed on various interweaved mappings, including written, mapped, hole, and unwritten. We also test large atomic writes on a heavily fragmented filesystem. These tests are separated into reflink (shared) and non-reflink tests. Signed-off-by: "Darrick J.
