I've currently posted all patches in my working tree, but review says I
need another round of review before it gets merged:
https://lists.gnu.org/archive/html/qemu-devel/2016-05/msg03569.html
https://lists.gnu.org/archive/html/qemu-devel/2016-06/msg03900.html

I'm also one or two patches shy of being able to use one union type as
the branch of another flat union type, where I still have to write the
patch, but it should be easy on top of the qapi patches that have landed
so far.

I also know that we want to get NBD converted for blockdev-add at the
same time, and that NBD, gluster, sheepdog, and other network-based
devices will share similar issues, so on my plate is to review this series:
https://lists.gnu.org/archive/html/qemu-devel/2016-04/msg01048.html

Can you please point me to the last proposal for gluster, and/or repost
any series you have for proposing the idea?  I want to help get working
blockdev-add into 2.7 if at all possible.
