NAME

       hlist_add_after_rcu - adds the specified element to the specified hlist

SYNOPSIS

       void hlist_add_after_rcu  (struct hlist_node * prev,
                                   struct hlist_node * n);

ARGUMENTS

       prev   the existing element to add the new element after.

       n      the new element to add to the hash list.

DESCRIPTION

       The  caller  must  take  whatever  precautions  are  necessary (such as
       holding appropriate locks) to avoid racing with  another  list-mutation
       primitive, such as hlist_add_head_rcu or hlist_del_rcu, running on this
       same list. However, it is perfectly legal to run concurrently with  the
       _rcu  list-traversal primitives, such as hlist_for_each_entry_rcu, used
       to prevent memory-consistency problems on Alpha CPUs.
