[PATCH] Btrfs: barrier before waitqueue_active
We need an smb_mb() before waitqueue_active to avoid missing wakeups. Before Mitch was hitting a deadlock between the ordered flushers and the transaction commit because the ordered flushers were waiting for more refs and were never woken up, so those smp_mb()''s are the most important. Everything else I added for correctness sake and to avoid getting bitten by this again somewhere else.
