A versions [squeeze through sid] have a line reading"The proper way to read records from fstab is to use the routines getmn-" . The next line begins with "tent(3)" ostensibly linking to a manpage for
"tent(3)".
See http://manpages.debian.org/cgi-bin/man.cgi?query=fstab&apropos=0&sektion=0&manpath=Debian+8+jessie&format=html&locale=en as example.
Intended target is manpage for GETMNTENT(3) [linked correctly under "SEE ALSO"].
