From: Joonsoo Kim <[email protected]> If we move an item on qlist's tail, we need to update qlist's tail properly. curr->next can be NULL since it is singly linked list so it is invalid for tail. curr is scheduled to be moved so using prev would be correct.
Unfortunately, I got this bug sometime ago and lose oops message. But, the bug looks trivial and no need to attach oops.
