migration/multifd: SYNC packet changes
https://lore.kernel.org/r/20230922145319.27380-1-farosas@suse.de
Here are the patches I mentioned in our discussion in the other
thread. The main purpose of this series is to be a PoC on how we can
move some stuff around and avoid taking the channel params lock.
I'm also trying to show that sem_sync on the sending side could be
made a bit more useful by using it to inform completion of any batch
of packets, rather than only completion of the SYNC packet.
I understand this is a disruptive series, so let's take it slow.
Thanks!
