    Too bad...

    Well, is there a way to avoid read_lock when reading list?

    Currently, TOMOYO Linux avoids read_lock, on the assumption that
    (1) First, ptr->next is initialized with NULL.
    (2) Later, ptr->next is assigned non-NULL address.
    (3) Assigning to ptr->next is done atomically.

    Regards.
