| 2016-11-10 | nvme: introduce struct nvme_request | Christoph Hellwig | |
| This adds a shared per-request structure for all NVMe I/O. This structure is embedded as the first member in all NVMe transport drivers request private data and allows to implement common functionality between the drivers. The first use is to replace the current abuse of the SCSI command passthrough fields in struct request for the NVMe command passthrough, but it will grow a field more fields to allow implementing things like common abort handlers in the future. The passthrough commands are handled by having a pointer to the SQE (struct nvme_command) in struct nvme_request, and the union of the possible result fields, which had to be turned from an anonymous into a named union for that purpose. This avoids having to pass a reference to a full CQE around and thus makes checking the result a lot more lightweight.

| 2016-07-05 | nvmet: add a generic NVMe target | Christoph Hellwig | |
| This patch introduces a implementation of NVMe subsystems, controllers and discovery service which allows to export NVMe namespaces across fabrics such as Ethernet, FC etc. The implementation conforms to the NVMe 1.2.1 specification and interoperates with NVMe over fabrics host implementations. Configuration works using configfs, and is best performed using the nvmetcli tool from http://git.infradead.org/users/hch/nvmetcli.git, which also has a detailed explanation of the required steps in the README file.
