What about

/**
 * slist_del -  remove an entry from list
 * @buf:        a storage area, just as long as the entry
 * @entry:      entry to be removed
 */
#define slist_del(_entry_in,_buf)			\
do {							\
	typeof(_entry_in) _entry = (_entry_in),		\
			  _head = (_buf), _free;	\
	memcpy(_head, _entry, sizeof(_entry));		\
	_free = _entry;					\
	_entry = _entry->next;				\
	_head->next = NULL;				\
	(_buf) = _head;					\
} while (0)

?
