-Subject: [PATCH] swait: Add memory barrier before checking list empty
-
-There's a race condition with swait wakeups and adding to the list. The
-__swait_wake() does a check for swait_head_has_waiters(), and if it is
-empty it will exit without doing any wake ups. The problem is that the
-check does not include any memory barriers before it makes a decision
-to wake up or not.
-
-	CPU0				CPU1
-	----				----
-
-  condition = 1
-
-  load h->list (is empty)
-				    raw_spin_lock(hlist->lock)
-				    hlist_add();
-				    __set_current_state();
-				    raw_spin_unlock(hlist->lock)
-  swait_wake()
-   swait_head_has_waiters()
-   (sees h->list as empty and returns)
-
-				    check_condition (sees condition = 0)
-
-   store condition = 1
-
-				    schedule()
-
-Now the task on CPU1 has just missed its wakeup. By adding a memory
-barrier before the list empty check, we fix the problem of miss seeing
-the list not empty as well as pushing out the condition for the other
-task to see.

-Subject: [PATCH] swait: Add smp_mb() after setting h->list
-
-The raw_spin_unlock() is not a full memory barrier. It only keeps
-things from leaking past it, but does not prevent leaks from entering
-the critical section. That is:
-
- 	p = 1;
-
- 	raw_spin_lock();
- 	[...]
- 	raw_spin_unlock();
-
- 	y = x
-
- Can turn into:
-
-  	p = 1;
-
- 	raw_spin_lock();
-
- 	load x
-
- 	store p = 1
-
- 	raw_spin_unlock();
-
- 	y = x
-
-This means that the condition check in __swait_event() (and friends)
-can be seen before the h->list is set.
-
- 	raw_spin_lock();
-
- 	load condition;
-
- 	store h->list;
-
- 	raw_spin_unlock();
-
-And the other CPU can see h->list as empty, and this CPU see condition
-as not set, and possibly miss the wake up.
-
-To prevent this from happening, add an mb() after setting the h->list.
