That I think is a 2.5 problem. One thing that has been talked about several times now is removing all the swap special case crap from the mm and making swap a file system. That removes special cases and means anyone can write or use custom, or multiple swap filesystems, in theory including things like swap over a shared GFS pool But its not for 2.4, no way Alan -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
