Hi Matthew,
I have several questions:
1) Do you have plans to add nore SG_* ioctls to supports more commands
from sg utils package?
2) Do you have plans to add/move more stuff to sysfs?
Thanks,
D

I don't have any plans to do anything further with the nvme-scsi driver
myself. I don't keep track of what is and isn't supported. That said,
if someone wants to send patches to add support for something that's
missing, I don't have a problem with applying it. For example, Keith
added support for UNMAP.

I'm open to exposing more stuff through sysfs. Did you have any requests?

I have been testing changes that expose the I/O queues through sysfs. At
this point, I have the entry 'reset' under
/sys/bus/pci/devices/<addr>/nvme_queues/Qn/ for each I/O queue.
Echoing a 1 to the reset file causes the I/O queue to be re-created as
described in section 7.3.3 in the NVMe 1.1 spec. This could be extended to
add other attributes of the queues, if there are any suggestions.
I'm planning on submitting a patch, but i need to cachup with the latest
changes, and I think that some of Keiths recent patches may affect what I
wrote. Specifically, he added the ability to suspend a queue. I was
planning on merging what i have done in with Keiths changes, perhaps
exposing 'suspend', along with 'reset' in sysfs
