This patch set fixes problems with pointer arithmetics overflow in llist iterators, llist_for_each_entry() and llist_for_each_entry_safe(). Clang turns those macros into infinite loops, because they're operating with "negative" pointers.
As a follow-up it may make sense to convert other uses of llist_entry() to llist_entry_safe(), or even replace uses of container_of() with container_of_safe().
