To make the ABI clean on some architectures, it's good to consider a 64-bit value only in positions where they map to an even:odd register pair once slotted in. > Yes, this was discussed before in the context of Pavel Emelyanov's patch > > http://lkml.org/lkml/2008/1/16/109 > > along with sys_indirect().

That's not really an open-ended interface, it's just an expandable bitmap. -hpa _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/containers
