Hi,

These patches enable asynchronous fetch for the pages that were not
accessed by the restored process.

Until now once we've started to fetch an iovec we've been waiting until
it's completely copied before returning to event processing loop. Now we
can have several request for the remote pages in flight.

Mike Rapoport (2):
  lazy-pages: make the check for outstanding request more strict
  lazy-pages: handle_remaining_pages: enable asynchronous reads
