Alfred Perlstein fb6d83aa60 Document VFS changes:
VFS_CHECKEXP.9, now used to check export credentials
VFS_FHTOVP.9, only used for filehandle to vnode, no access checks are done.
VFS.9, inform people of the vfs_std* functions available to avoid
       ugly casts to eopnotsup and making of dummy functions to return 0.

.Sh NAME
.Nm VFS
.Nd kernel interface to filesystems
.Sh DESCRIPTION
Calls used to set or query filesystems for settings or information.
.Pp
Filesytems that don't implement a VFS operation should use the appropriate
.Fa vfs_std
function from
.Fa src/sys/vfs_defaults.c
rather than implementing empty functions or casting to
.Fa eopnotsupp .
