It's efficient, but hackish to call yank unregister calls in channel_close(), especially it'll be hard to debug when qemu crashed with some yank function leaked. Remove that hack, but instead explicitly unregister yank functions at the places where needed, they are: (on src) - migrate_fd_cleanup - postcopy_pause (on dst) - migration_incoming_state_destroy - postcopy_pause_incoming Signed-off-by: Peter Xu <peterx@redhat.com> Message-Id: <20210722175841.938739-6-peterx@redhat.com> Reviewed-by: Lukas Straub <lukasstraub2@web.de> Signed-off-by: Dr. David Alan Gilbert <dgilbert@redhat.com>
