File2 Code:

fn_test()

echo $tmp
}
echo test

Ok

Doesn't suppress execution of commands outside function definitions, this can be very dangerous."
means you have just echo statement in your file2 but what if you have some other command lets say "rm".Your intention was just to execute the function not the rm command then >/dev/null will not help it will just redirect out put to nowhere but it certainly execute the rm command.
What Vino is suggested is the standard way and you can always modify to that.
If you only have echo commands and not any harmful commands in that file than this >/dev/null will do fine and widely used.

vfs_checkexp

VFS_CHECKEXP(9) 					   BSD Kernel Developer's Manual					   VFS_CHECKEXP(9)

NAME

     VFS_CHECKEXP -- check if a file system is exported to a client

SYNOPSIS

     #include <sys/param.h>
     #include <sys/mount.h>

     int
     VFS_CHECKEXP(struct mount *mp, struct sockaddr *nam, int *exflagsp, struct ucred **credanonp);

DESCRIPTION

     The VFS_CHECKEXP() macro is used by the NFS server to check if a mount point is exported to a client.

     The arguments it expects are:

     mp 	The mount point to be checked.

     nam	An mbuf containing the network address of the client.

     exflagsp	Return parameter for the export flags for this client.

     credanonp	Return parameter for the anonymous credentials for this client.

     The VFS_CHECKEXP() macro should be called on a file system's mount structure to determine if it is exported to a client whose address is con-
     tained in nam.

     It is generally called before VFS_FHTOVP(9) to validate that a client has access to the file system.

     The file system should call vfs_export_lookup(9) with the address of an appropriate netexport structure and the address of the client, nam,
     to verify that the client can access this file system.

RETURN VALUES

     The export flags and anonymous credentials specific to the client (returned by vfs_export_lookup(9)) will be returned in *exflagsp and
     *credanonp.
