That is a special case of the proposed solution. You could mlock the regions of interest. Those can then only be migrated but not swapped out. However, I think we need some limit on the number of pages one can mlock. Otherwise the VM can get into a situation where reclaim is not possible because the majority of memory is either mlocked or pinned by I/O etc. _______________________________________________ general mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
