list: Use WRITE_ONCE() when initializing list_head structures
Code that does lockless emptiness testing of non-RCU lists is relying on INIT_LIST_HEAD() to write the list head's ->next pointer atomically, particularly when INIT_LIST_HEAD() is invoked from list_del_init(). This commit therefore adds WRITE_ONCE() to this function's pointer stores that could affect the head's ->next pointer. Reported-by: Andrey Konovalov <andreyknvl@google.com> Signed-off-by: Paul E.
