[nvmewin] OFA Release Plan: Release #1 2015 -- Call for patch volunteers

[Iuliu Rus]

Raymond, we are running the windows HCK fuzz test on the driver and it
exposes several crashes. Also, on SCSIOP_START_STOP_UNIT it looks
like SntiTransitionPowerState builds an io which it never submits, causing
Windows to eventually reset the adapter.
Given that some of these fuzz crashes are potential security issues, we are
getting ready to submit the patch next week. However it is rather big and
the current patch submission process doesn't work that well. We would like
to break it into separate changes, but with zipped thrunk this is not
possible. Is there any way to switch this over to github so we can use pull
requests instead? Or, should we do separate submissions for now?
