It actually shouldn't slow it down. kfree already complains if you free a non slab page, this could be just in front of the error check. The bigger concern is that it may hide some programing errors elsewhere though. So it's probably better to keep it a separate function. -Andi -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
