The summary mentions 'df -l', which is mapped to the show_local_fs flag.  
However, the condition you are adding does not use the flag at all.  Why?

The condition already contains a special handling for 'df -l':

    (me->me_remote && show_local_fs)

Why does not it work without your patch?

How exactly looks the mount entry you want to skip the stat() call for?

What is the full content of *me in this case?

Is there a good reason for http://bugzilla.suse.com/show_bug.cgi?id=1043059 
not being accessible for free?
