Please, try to apply this hunk:

diff --git a/criu/autofs.c b/criu/autofs.c
index 1c7c126..606e744 100644
--- a/criu/autofs.c
+++ b/criu/autofs.c
@@ -70,8 +70,8 @@ int autofs_parse(struct mount_info *pm)
         free(opts);

         if (pipe_ino == AUTOFS_OPT_UNKNOWN) {
-               pr_err("Failed to find pipe_ino option (old kernel?)\n");
-               return -1;
+               pr_warn("Failed to find pipe_ino option (old kernel?)\n");
+               return 0;
         }

         return autofs_gather_pipe(pipe_ino);
