[PATCH 0/7] nvmet: support of Fused operations

[Dmitry Bogdanov]

Hi,

This patchset introduces a support of Atomic Test & Set (ATS) primitive.
It's implemented by means of Compare And Write fused commands in nvme target.

That allows ESXi to use Linux NVME Target as VMFS datastore storage.

The first 3 patches add a single Compare command support.
4th patch an refactoring to have a common point in the command execution flow.
5,6 patches adds support of Fused commands.
And the last patch allows to send fused commands by nvme io-passthru tool
for testing purposes.

The patchset based on nvme-6.12.

Dmitry Bogdanov (7):
  nvmet: add support of Compare command
  nvmet: bdev: add support of Compare command
  nvmet: file: add support of Compare command
  Revert "nvmet: Open code nvmet_req_execute()"
  nvmet: add support of fused operations
  nvmet: make fused commands be atomic
  nvme: allow send fused commands
