[PATCH 00/17] block/nvme: Various cleanups required to use multiple queues

[Philippe Mathieu-Daudé]

Hi,

This series is mostly code rearrangement (cleanups) to be
able to split the hardware code from the block driver code,
to be able to use multiple queues on the same hardware, or
multiple block drivers on the same hardware.

Flushing my current patch queue.

Regards,

Phil.
