The last time this came up I said that the kernel side of ibv_reg_mr

device (video) memory to userspace, so it can be done safely.

Tom posted changes to support this a while back. Tom, do you have an
updated patch series for this support?
Yes. I removed the new verb and followed Jason's recommendation of adding
this support to the core reg_mr support. I used the type bits in the vma
struct to determine the type of memory being registered and just did the
"right thing."
I'll repost in the the next day or two.
