Its no longer easy to see what work is left so I started a new ticket to track the remaining work, LU-9679. Please migrate to that ticket.

[James A Simmons]

My bad. Wrong ticket number was used by mistake. Now its under LU-8056.

Future kernel patches are being directed to separate tickets. Currently kernel 4.5 support is being done under LU-8056. This ticket is really meant to be a task tracking ticket for the upstream <-> master work.

[Peter Jones]

I cannot mark the ticket as resolved because it has technical tasks still open so I have removed the 2.9 fixversion. IMHO the best thing to do from a tracking point of view would be to have a ticket for each kernel version so it is really clear to understand which patches are needed for a given kernel version.

[James A Simmons]

I first need to open the new ticket and add all the open links on this ticket to that new one.

[Andreas Dilger]

If all of the current patches are landed, it would be best to close this bug for 2.9.0 and open a new one for 2.10.0 (linked to this one). That makes it a lot easier to track.

[Jian Yu]

Hi James,
So far, all of the existing patches for this ticket have landed. Are there any new patches?
