->permission and ->lookup have a struct nameidata * argument these days to pass down lookup intents. Unfortunately some callers of lookup_hash don't actually pass this one down. For lookup_one_len() we don't have a struct nameidata to pass down, but as this function is a library function only used by filesystem code this is an acceptable limitation. All other callers should pass down the nameidata, so this patch changes the lookup_hash interface to only take a struct nameidata argument and derives the other two arguments to __lookup_hash from it. All callers already have the nameidata argument available so this is not a problem. At the same time I'd like to deprecate the lookup_hash interface as there are better exported interfaces for filesystem usage. Before it can actually be removed I need to fix up rpc_pipefs.
