[PATCH v8 0/5] hw/block/nvme: dulbe and dsm support

From: Klaus Jensen
Subject: [PATCH v8 0/5] hw/block/nvme: dulbe and dsm support
Date: Thu, 12 Nov 2020 20:59:40 +0100

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

This adds support for the Deallocated or Unwritten Logical Block error
recovery feature as well as the Dataset Management command.

  - Move req->opaque clearing to nvme_req_clear.
  - Add two preparation/cleanup patches.

  - Handle negative return value from bdrv_block_status.
  - bdrv_get_info may not be supported on all block drivers, so do not
    consider it a fatal error.

  - Skip the allocation of the discards integer and just use the opaque
    value directly (Philippe)
  - Split changes to include/block/nvme.h into a separate patch
  - Clean up some convoluted checks on the discards value (Philippe)
  - Use unambiguous units in the commit messages (Philippe)
  - Stack allocate the range array (Keith)

  - Restore status code from callback (Keith)

  - Removed mixed declaration and code (Keith)
  - Set NPDG and NPDA and account for the blockdev cluster size.

Klaus Jensen (5):
  hw/block/nvme: remove superfluous NvmeCtrl parameter
  hw/block/nvme: pull aio error handling
  hw/block/nvme: add dulbe support
  nvme: add namespace I/O optimization fields to shared header
  hw/block/nvme: add the dataset management command
