I can give it a try, but I don't see why it would make any difference. Swap files bypass the filesystem completely during the I/O phase as the swap code builts an extent map during swapon and then submits bios by itself. That also means no allocator calls or other forms of metadata updates. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxxx For more info on Linux MM, see: http://www.linux-mm.org/ .
