[PATCH v7 00/48] nvme: support NVMe v1.3d, SGLs and multiple namespaces

[Klaus Jensen <its@irrelevant.dk>]

From: Klaus Jensen <k.jensen@samsung.com>

Hi,

v7 is mostly just changes proposed by Maxim. Also, Gollu's patch for the
bit bucket sgl descriptor has been added (patch #43), but it is of a
pretty manageable size.



Changes since v6
~~~~~~~~~~~~~~~~

* 01/48 ("nvme: rename trace events to nvme_dev")
  - indentation nitpicks (Maxim)

* 04/48 ("nvme: bump spec data structures to v1.3")
  - added defines for temperature threshold and sensor selection (Maxim)
  - added defines for the EUI64 and NGUID NIDT types (Maxim)

* 09/48 ("nvme: add max_ioqpairs device parameter")
  - hoisted a bugfix out (Maxim)

* 11/48 ("nvme: refactor device realization")
  - pulled the removal of the duplicated cmbsz/cmbloc struct members to
    separate patch (Maxim)
  - fixed an incomplete error message (Maxim)

* 12/48 ("nvme: add temperature threshold feature")
  - use the defines added in 04/48 (Maxim)
  - remove the addition of the unused 'temperature' NvmeCtrl member

* 13/48 ("nvme: add support for the get log page command")
  - use the already defined NvmeErrorLog type (Maxim)
  - add the 'temperature' NvmeCtrl member here instead (Maxim)

* 15/48 ("nvme: add missing mandatory features")
  - fix off-by-one when validating dw11 for the interrupt vector config
    feature (Maxim)
  - some nitpicks (Maxim)

* 16/48 ("nvme: additional tracing")
  - moved some traces (that was added in later patches) to here

* 19/48 ("nvme: support identify namespace descriptor list")
  - refactored for the nth time; I think I'm finally kind of happy with
    it

* 20/48 ("nvme: enforce valid queue creation sequence")
  - added a comment (Maxim)

* 24/48 ("nvme: add mapping helpers")
  - fixed an off-by-one error that would cause valid read/writes to the
    CMB to be rejected (Maxim)
  - add a check on len so we don't add 0 sized elements to the iovec
    (Maxim)

* 26/48 ("nvme: remove redundant has_sg member")
  - pulled the s/dma_acct/block_acct change to a separate patch (Maxim)

* 36/48 ("nvme: allow multiple aios per command")
  - renamed nvme_req_register_aio to nvme_req_add_aio and added some
    comments (Maxim)
  - killed the prinfo patch
  - pulled a bunch of refactoring stuff into other patches to make this
    one easier to read (Maxim)

* 42/48 ("nvme: add support for scatter gather lists")
  - pulled the nvme_addr_read hardening into its own patch (Maxim)
  - refactored the logic around allowed sgl descriptor types (Maxim)
  - additional comments (Maxim)

* 45/48 ("nvme: support multiple namespaces")
  - fix an inconsistent return value
  - fix an edge error case where all namespaces are allocated (Maxim)
