Jason, can you queue this up for 5.5 to reduce this patch stack a bit?
Yes, I said I'd do this in an earlier revision. Now that it is clear this won't go through Andrew's tree, applied to rdma for-next
Great, I'll plan on it going up through that tree. To be clear, is it headed for:
git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma.git for-next
?
thanks,
