That is indeed what I meant. It's not 100% identical as aliases dirty logging will go to the underlying slot, whereas with two slots mapping the same range it's undefined which will get the dirty bits set, but userspace can probably handle this easily. -- Any sufficiently difficult bug is indistinguishable from a feature. ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
