    partially fix up the lookup_one_noperm mess · eead1911
    Christoph Hellwig authored
    Try to fix the mess created by sysfs braindamage.
    
     - refactor code internal to fs/namei.c a little to avoid too much
       duplication:
    	o __lookup_hash_kern is renamed back to __lookup_hash
    	o the old __lookup_hash goes away, permission checks moves to
    	  the two callers
    	o useless inline qualifiers on above functions go away
     - lookup_one_len_kern loses it's last argument and is renamed to
       lookup_one_noperm to make it's useage a little more clear
     - added kerneldoc comments to describe lookup_one_len aswell as
       lookup_one_noperm and make it very clear that no one should use
       the latter ever.
