Take a look at the file Documentation/filesystems/porting in the 2.6 
kernel source tree.

 From Documentation/filesystems/porting:

"->revalidate() is gone.  If your filesystem had it - provide 
->getattr()
and let it call whatever you had as ->revlidate() + (for symlinks that
had ->revalidate()) add calls in ->follow_link()/->readlink()."

The struct nameidata holds the struct dentry and struct vfsmount.  I 
think you can safely ignore the new parameter (neither proc_lookup not 
devfs_lookup use the nameidata parameter).
