      nvme: don't pass the full CQE to nvme_complete_async_event · 7bf58533
      Christoph Hellwig authored
      
      We only need the status and result fields, and passing them explicitly
      makes life a lot easier for the Fibre Channel transport which doesn't
      have a full CQE for the fast path case.

      nvme: introduce struct nvme_request · d49187e9
      Christoph Hellwig authored
      
      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.
