[PATCH v3 blktests 0/2] Add atomic write tests for scsi and nvme

[Alan Adamson]

Changes in v3:
- Remove _have_xfs_io routine and use _have_program.
- Comment cleanup in 0001
- Add SKIP_REASONS when xfs_io -A option is absent.
- Keep lines <=80 characters.
- Move device_requires logic in 0001 and 0002 to common/rc.

Changes in v2:
- Add additional comments in common/xfs
- Remove xfs_io and kernel version checking
- Simplify paths for sysfs attributes
- Fix failed case output (missing echo) in scsi/009
- Add local variable that sets Test # and description (test_desc) for scsi/009 and nvme/059
- Only use scsi_debug device if no scsi test device is provided.
- nvme testing done with qemu-nvme.
- scsi testing done with scsi_debug and qemu-scsi (no atomic write support).  No testing on
  atomic write capable scsi devices was done.
-------------------------------------------------------------------------------------------
Add tests for atomic write support.

Tests will be delivered for scsi (using scsi_debug) and nvme.  NVMe can use the qemu-nvme
emulated device that supports Controller-based Atomic Parameters (QEMU 9.2).

The xfs_io utility delivered with the xfsprogs-devel package (version 6.12) is required by
these tests.

The Linux Kernel 6.11 (and greater) supports Atomic Writes and is required by these tests.
