    [PATCH] reiser4: add radix_tree_lookup_slot() · a4331366
    Hans Reiser authored
    Reiser4 uses radix trees to solve a trouble reiser4_readdir has serving nfs
    requests.
    
    Unfortunately, radix tree api lacks an operation suitable for modifying
    existing entry.  This patch adds radix_tree_lookup_slot which returns pointer
    to found item within the tree.  That location can be then updated.
    
    Both Nick and Christoph Lameter have patches which need this as well.
