Did you see Nathan's reply not long ago, confirming that it doesn't stop all activity if you don't freeze bdevs? That isn't critical for swsusp (although I guess you could end up with some filesystem inconsistency if XFS writes something after the atomic copy), but keeping the LRU static is important for suspend2." In another email, I mentioned that trying to free memory with swap on a journalled filesystem is a potential deadlock situation without the capability of thawing kernel threads alone. You could potentially thaw all threads while eating memory, but then there's a greater chance of racing against another program that's trying to allocate memory (if you're in this situation, you're low on memory to start with).
