    Introduce a handy list_first_entry macro · b5e61818
    Pavel Emelianov authored
    There are many places in the kernel where the construction like
       foo = list_entry(head->next, struct foo_struct, list);
    are used.
    The code might look more descriptive and neat if using the macro
       list_first_entry(head, type, member) \
                 list_entry((head)->next, type, member)
    Here is the macro itself and the examples of its usage in the generic code.
     If it will turn out to be useful, I can prepare the set of patches to
    inject in into arch-specific code, drivers, networking, etc.
