seems that patch 1 (the pushdown) did not yet made it to the list. Looking at
you diffstat it seems that you only touched fs/*

There are filesystems in other places, e.g.

I am really not an expert in filesystems, so my comment might be bogus: My
expection was, that a simple pushdown should also affect these filesystems,
especially if the filesystems dont use simple_fill_super, no?
