I will make these changes, but to clarify do you want us to carry a full
kernel repo upstream or can we just carry the target-pending?


It's useful to have a tree based on linux.git to PULL from for early
developments, but it's just for WIP code ahead of an initial upstream
driver merge.


I was wondering how you would like WIP code reviewed? I have created a pull
request against my own development branch which is a branch of for-next
with some initial changes. https://github.com/powervm/ibmvscsis/pull/5
Let me know if that is how you want code reviewed.

Also I have created Wiki's that contain config files for targetcli/WIP Log.

Lastly, I was wondering if we can remove handle_cmd_queue()? I think it would be
better to re-write some of the queue handling so that we aren't spinning.
https://git.kernel.org/cgit/linux/kernel/git/nab/target-pending.git/tree/drivers/scsi/ibmvscsi/ibmvscsis.c?h=for-next-vscsi#n1428

Also, do you know if host aka ibmvscsi is supposed to add something into our queue
asking for what we have attached aka luns in this scenario? I would think
after login, they should add a queue to ask the target what we have?

Thanks,

Bryant
