[nvmewin] OFA NVMe Windows Driver Release Consolidation for 2015

[Robles, Raymond C]

All,

In 2015, we've seen a pretty severe drop-off in patch contributions up to this point in the year.  In 2014, there were many patch submissions, and I think it was likely due to many companies working towards product releases (which we've seen quite a few of this year... as well as last year). It has been great to see the ecosystem adopt NVMe.

Now that the "traffic" has slowed down on the distribution list, I've consulted with the four reviewing companies and we have decided that we will consolidate our two original releases and will have just one release for 2015. This release will happen at the end of 2015 and we will roll in all patches submitted up to this point in time. The original patch schedule is included below. Note that bug fix patches are not included in this schedule.

Code Reviewing Companies:

-          PMC Sierra

-          HGST

-          Samsung

-          Intel

Please let me know if you have any questions.
