    cifs: convert tlink_tree to a rbtree · b647c35f
    Jeff Layton 提交于
    Radix trees are ideal when you want to track a bunch of pointers and
    can't embed a tracking structure within the target of those pointers.
    The tradeoff is an increase in memory, particularly if the tree is
    sparse.
    
    In CIFS, we use the tlink_tree to track tcon_link structs. A tcon_link
    can never be in more than one tlink_tree, so there's no impediment to
    using a rb_tree here instead of a radix tree.
    
    Convert the new multiuser mount code to use a rb_tree instead. This
    should reduce the memory required to manage the tlink_tree.
