OGAWA Hirofumi be3b075354 [PATCH] cfq: Further rbtree traversal and cfq_exit_queue() race fix ... In current code, we are re-reading cic->key after dead cic->key check. So, in theory, it may really re-read *after* cfq_exit_queue() seted NULL. To avoid race, we copy it to stack, then use it. With this change, I guess gcc will assign cic->key to a register or stack, and it wouldn't be re-readed.
