list: Use WRITE_ONCE() when adding to lists and hlists Code that does lockless emptiness testing of non-RCU lists is relying on the list-addition code to write the list head's ->next pointer atomically. This commit therefore adds WRITE_ONCE() to list-addition pointer stores that could affect the head's ->next pointer. Reported-by: Dmitry Vyukov <dvyukov@google.com> Signed-off-by: Paul E.
