[PATCH v6 00/42] nvme: support NVMe v1.3d, SGLs and multiple namespaces

[Klaus Jensen]

From: Klaus Jensen <address@hidden>

Hi,

So this patchset kinda blew up in size (wrt. number of patches) after
Maxim's comments (26 -> 42), but Maxim's comments about splitting up a
bunch of the patches made a lot of sense.

v6 primarily splits up the big nasty patches into more digestible parts.
Specifically the 'nvme: refactor prp mapping' and 'nvme: allow multiple
aios per command' patches has been split up according to Maxim's
comments. Most additions to the shared include/block/nvme.h has also
been consolidated into a single patch (also according to Maxim's
comments). A lot of the patches still carries a 'Reviewed-By', but
git-backport-diff reports some changes due to changes/additions in some
of the early patches.

The only real "addition" is a new "max_ioqpairs" parameter for the
device. This is to fix some confusion about the current "num_queues"
parameter. See "nvme: add max_ioqpairs device parameter".

Maxim, I responded to your comments in the original thread and I believe
that all your comments has been adressed.

Also, I *did* change the line indentation style - I hope I caught 'em
all :)
