I think I'd fix this typo in a separate commit, since it's a meaningful
typo (both EMFILE and ENFILE exist, and they have a slightly different
meaning).

In the fix, please include the following tags:

	Fixes: ac5edfeb1dd6 (2021-08-27; "memfd_secret.2: New page describing memfd_secret() system call")
	Cc: Mike Rapoport <rppt@linux.ibm.com>

This seems to also exist in the kernel internal documentation.  I've
CCd the maintainers of that documentation.

	$ find Documentation/ | grep landlock | xargs grep OverlayFS
	Documentation/userspace-api/landlock.rst:Bind mounts and OverlayFS
	Documentation/userspace-api/landlock.rst:An OverlayFS mount point consists of upper and lower layers.  These layers are
	Documentation/userspace-api/landlock.rst:on the upper layer.  From a Landlock policy point of view, all OverlayFS layers
	Documentation/userspace-api/landlock.rst:OverlayFS layer will not restrict the resulted merged hierarchy, and vice versa.

Have a lovely day!
