This is independent patch, I don't have any concern to drop this patch.

Small nit: Since Documentation patch is later in series, its mentioned
in the doc. One line need to be removed from vfio-mediated-device.txt.

--- a/Documentation/vfio-mediated-device.txt
+++ b/Documentation/vfio-mediated-device.txt
@@ -150,7 +150,6 @@ The callbacks in the parent_ops structure are as
follows:
 * read : read emulation callback
 * write: write emulation callback
 * mmap: mmap emulation callback
-* notifier: notifier callback
