I am not sure I completely understand the intentions behind this.

So it sounds like the uffd daemon running on the same side as the
restore process, because right now we only have local lazy-restore,
does not terminate after handling all page-requests from one restore.
Which sounds good. But right now the part started with 'criu lazy-pages'
still needs a checkpoint directory where it can read the checkpoint
files. I haven't seen the point where the 'criu lazy-pages' part gets
the new directory FD.

I don't have anything against this patch series, but this somehow is a
decision in favor of a 'dumb' 'criu lazy-pages' which only forwards the
requests from the network to the UFFD. As this is also my preferred
solution I am happy to go this way, but from my point of view this
somehow shortcuts our other discussion thread. If this is the way we
want to continue then these patches are a good step in the right
direction.
