Sloppy writing: insert "with the exception of filesystems that are not
going to be suitable for any form of stacking" - there _is_ a bunch of
debugfs, configfs, kernfs places using that.  They'd also better be
taken care of, but it's an independent story; for overlayfs/unionmount/etc.
purposes they are non-issue.

BTW, there are several places where ->f_path.mnt access is the right thing
to do - in autofs.  Also a non-issue here...
