hlist_nulls_entry_safe

#define hlist_nulls_entry_safe	(		ptr,
			type,

	)

Value:

    })

hlist_nulls_for_each_entry

#define hlist_nulls_for_each_entry	(		tpos,
			pos,
			head,
			member
	)

Value:

    for (pos = (head)->first;                          \
         (!is_a_nulls(pos)) &&                         \

hlist_nulls_for_each_entry - iterate over list of given type @tpos: the type * to use as a loop cursor. @pos: the &struct hlist_node to use as a loop cursor. @head: the head for your list. @member: the name of the hlist_node within the struct.

hlist_nulls_for_each_entry_from

#define hlist_nulls_for_each_entry_from	(		tpos,
			pos,
			member
	)

Value:

    for (; (!is_a_nulls(pos)) &&                \
        ({ tpos = hlist_nulls_entry(pos, typeof(*tpos), member); 1;}); \
         pos = pos->next)

hlist_nulls_for_each_entry_from - iterate over a hlist continuing from current point @tpos: the type * to use as a loop cursor. @pos: the &struct hlist_node to use as a loop cursor. @member: the name of the hlist_node within the struct.
