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)

?
