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

Thu May 14 22:52:56 PDT 2015

Hello,

We always welcome companies to submit patches for candidate features. No other company has volunteered for concurrent channels at this time. We would gladly welcome your patch at your earliest convenience. The first release for 2015 is planned for ~August/September... would you like to volunteer for this patch prior to this release?

As for a race condition synchronization fix for FreeQList, could you please describe the issue you were seeing and how you addressed it?

Thanks,
Ray

Hello,
We are the google compute engine team and we already have Concurrent channels working. We're still figuring out how we can integrate between our internal repo and svn.
Do you still need this feature?
We also have a synchronization fix for a race that corrupted FreeQList.

All,

I just wanted to send out a quick update on the release plans for 2015. We’ve had two more companies volunteer to submit patches this year: Samsung (Suman) and HGST (Tom). Thank you to both companies for volunteering!

Here is the updated release plan for 2015. Unfortunately, some of the patch submissions will be a little later than originally planned. Therefore, I would like to ask the question: is everyone ok if we push the first release out until end of August to allow for more patches to be submitted? You can response publicly or just to me.

Other alternatives would include just having smaller releases at different cadences. I’m open to any ideas since there are still many requests for features that have claimed for patch submission.

I would like to formally ask for volunteers for patch submissions. As of today, there are no volunteers for any of the below patches.

Intel would like to start with the volunteering… we will volunteer to provide the namespace management patch.
