How long will you be accepting patches to merge for? If its going
to be a few weeks like to just include the missing two patches with
the next batch.
Another issue I need to look at is the IB changes. That's going to
require some heavy surgery to the ko2iblnd driver so its going to
take time for me to port this to the new RDMA RW api. That will
need to be push to linus so ko2iblnd can work with the 4.9 tree
if that is okay with you.
