[PATCH v2 00/11] block/nvme: Rework error reporting

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

Hi,

This series contains various patches sent last year with
review comments addressed, few more cleanups, and a new
patch which remove the spurious "VFIO_MAP_DMA failed: No
space left on device" now poping up since commit 15a730e7a.
(it is the expected behavior, which is why we retry the
same call after flushing the DMA mappings).

Since v1:
- Addressed Klaus review comments (cleaner Error* handling)
- Add Klaus's R-b

Regards,

Phil.
