[0/9] block/nvme: Rework error reporting

Message

Philippe Mathieu-Daudé Aug. 24, 2021, 2:11 p.m. UTC

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).

Regards,

Phil.
