 then I'd propose to add this to struct nameidata:
 
 	char *ni_pathname;
 
 and this to NDINIT():
 
 	(ndp)->ni_pathname = NULL;
 
 and namei() to store the pathname in 'ni_pathname' if it's not NULL. so
 callers that want the path can just:
 
 	nd.ni_pathname = PNBUF_GET();
 
 and later free it. there's probably a better way to do this (without
 risking memory leaks) but I'm not familiar with namei() internals.
 
 for the meantime, I think we should use the patch I posted, at least for
 4.0, until we decide how to handle this otherwise.
